* Add support for flow type spread
* Broaden spreadable types from primary to all, more tests
* Eliminate variance sigil for type spreads, better errors, fix tests
* master:
Upgrade flow to 0.41
Throw error if new.target is used outside of a function (#402)
Fix watch command (#403)
Update yarn lock
Fix parsing of class properties (#351)
# Conflicts:
# src/parser/statement.js
# test/fixtures/experimental/class-constructor-call/illegal-key/options.json
* Fix negative number literal typeannotations
Also use parseLiteral() to parser string and number literal typeannotations
so that future changes (estree) to literals are also reflected to flow.
* Instead of invalid fallthrough throw immediately
* Increase coverage and better error mesage
* [Flow] Function predicate declaration
The accepted syntax for function declarations is extended to allow
the following predicate declaration:
FunctionReturnType :=
Type
Predicate
Type Predicate
Predicate :=
%checks
%checks ( ConditionalExpression )
* [Flow] Minor tweaks and more examples to function predicates
* [Flow] Clean-up and better message for function predicates
* [Flow] Adding abstract function predicate example
* [Flow] Rearranging the `predicate` field to ease babel generator.
* Parse flow nested array type annotations like number[][]
Fixes#217.
* Do not parse a newline separated array statement into a flow type annotation
* Get rid of lineBreak dependency in flow.js in favor of higher level method
* Use .gitattributes to ignore files with weird newlines
* [Flow] Make parameter names in function types optional
* [Flow] Anonymous function types with single params can omit parens
* [Flow] Optional names for object indexer keys
* Add noAnonFunctionType explicitly to state
* Adjust gitattributes as files have been fixed
* Increase test coverage
* Test for error when binding `this` in destructuring pattern
* Ignore coverage of inAsync check in parseAwait - already checked externally
* Ignore coverage of default case in checkPropClash
* Remove unused parameter isAsync from parseParenAndDistinguishExpression
* Ignore coverage of an `else` branch in flowParseTypeParameterDeclaration
* Flow: remove unused parameters to flowParseTypeAnnotatableIdentifier
* Flow: ignore coverage of pass-through throw statement in parseConditional
* Flow: Add test for error on property with type param
* Flow: ignore coverage of pass-through throw statements in parseMaybeAssign, parseArrow
* Add test for error on XML-style comment in module code
* Update test for error on method in object pattern
* Test for error: "Only '=' operator can be used for specifying default value"
* Property variance type annotations for Flow plugin
Non-method properties and indexers of object types, declare class, and
interfaces can be "positive" or "negative." Class fields, but again not
methods, can also have variance.
This PR generalizes the variance annotations for type parameters into a
new node type, and reuses that node for those properties.
The code for object types is reused for interfaces and declare classes.
The changes there are straightfoward.
The code for class fields is reused for object literals, which do not
support variance annotations (currently). This code is a bit sketchy,
because we always parse variance annotations in the `parsePropertyName`
extension, then error in a the subsequent parse phase for object
literals (`parseObjPropValue`) or class methods (`parseClassMethod`).
* Remove bogus unreachable code, clarify variance parsing conditional
* Don't use a new node type for variance annotations
Adding a new node type, specifically changing the TypeParameter node's
variance property to be node-valued, is a breaking change. We might
choose to make this breaking change in a later version.

I also noticed that there was missing test coverage for builtin types,
so I added a test for that, which includes the newly added type as well
as the other existing types.
* Rephrase "assigning/binding to rvalue" error messages with context (#119)
* Fix code style in parser/lval.js
* istanbul ignore some unused branches in parser/lval.js
* Fix code style again in parser/lval.js
* exact object type annotations for Flow plugin
* Couple tweaks per suggestions
* s/==/===/
* add test for unexpected token in flowObjectType Semicolon
This makes declare class extends behave the same way as in flow
The ast-token after the extends keyword, might be either Identifier or
QualifiedTypeIdentifier
To do that this commits splits the parseGenericType into two functions,
one for parsing genericType and on for qualifiedTypeIdentifier
