* Add stricter Optional Chain node validation
Optional chains cannot start with `optional: false`. Somewhere in the `object`/`callee` tree, there must be an optional with `optional: true`.
* Print current node's type when finding an error.
* Added support for record and tuple syntax.
This commit adds support for both the hash #{} and bar {||}
syntaxes to babel-parser, as well as adds the supporting
babel-plugin-syntax-record-and-tuple plugin to enable support
for the syntax. Does not include any transform for records and
tuples.
* typo
* added check to ensure recordAndTuple in babel-parser
* switched to syntaxType option instead of explicit entries for each record and tuple type
* switched to using recordAndTupleSyntaxType for generator options instead of adding to node
* added tests for generator option recordAndTupleSyntaxType
* added test for record and tuple bar syntax with flow typings
* added tests for invalid/missing recordAndTuple syntaxType parser option
* fixed flowcheck errors
* fix merge with class privates in tokenizer
* Update packages/babel-parser/src/types.js

* Update Purish aliases
- Adds `Purish` to `RegexLiteral`, since it can't cause any side-effects.
- Removes `Purish` from `ClassExpression` and `ClassDeclaration`, since they can be impure with static class fields.
* Update types
* Change isReferenced to return false for object/class method parameter names.
* use indexOf instead of for-of loop
* replace `.indexOf` check with `.includes` and assume `parent.params` exists

* check .params within case block for ClassMethod/ClassPrivateMethod/ObjectMethod only
* add comment clarifying that case clause fall-through is intentional

* Flow enums: use contextual utils, change members length checks to use logic operators, remove reserved word logic modification
* Flow enums: remove unnecessary code in generator, fix error message
This adds lots of missing declarations to the types of @babel/types,
including many utility functions useful to plugin authors.
With the typescript types, I tried to make them as useful as possible
for control flow analysis / inference, but Flow doesn't seem to
support overloads and I'm not as familiar with it anyway so it has
simpler types.
Flow maybe types state;
> Maybe types accept the provided type as well as null or undefined. So ?number would mean number, null, or undefined.
So in this case, explicitly allow the type, null, or undefined in the
typescript definition.
Fixes#10403
* feat: v8intrinsic syntax plugin
Implement V8 Intrinsic Syntax Extension. Here we check the execution branch inside the parseSubscript to make sure the V8IntrinsicIdentifier is immediately followed by a call expression.
* feat: disable combining placeholders and v8intrisic
per https://github.com/babel/babel/issues/10104#issuecomment-506950969
* test: add more error cases
* refactor: parse v8 intrinsic in parseExprAtom
This approach is identical to V8’s implementation. Move the test cases as the behaviour changes.
* fix: plugin-name typo
* test: add yield-expression test case
* feat: require startsExpr on modulo for v8intrinsic
* perf: skip eof and braceR check as they must return false
* Print V8IntrinsicIdentifier
* feat: add v8intrinsic to parser typings
* Add generated type helpers
* fix: incorrect type definition
* fix: allow V8IntrinsicIdentifier to be callee
