See eb815be907 for more information about this feature.
    
The proto modifier indicates that a property declared using `x: T` syntax is actually present on the prototype object of the class, rather than an own property.
    
The proto and static modifiers are mutually exclusive, as class declarations don't simultaneously define the static prototype object, as they do the instance prototype.
    
This syntax is only supported on declared classes, not object types, interfaces, or runtime class declarations, and as such should only appear in library definitions.

a40f54f847 Add support for explicit type arguments in new and call expressions (#7934)
* Add all option to babel-plugin-syntax-flow

The Flow parser has some conditional logic based on whether types should
be parsed or not, which is based on either (a) the @flow pragma in the
docblock of the file of (b) the `all` configuration, provided via
command line or .flowconfig.

This commit adds the ability to provide the `all` configuration to
Babel as well, via the syntax-flow plugin. This should be set to `true`
if the project uses all=true.

* Parse @flow pragma

The Flow parser has some conditional logic based on whether types should
be parsed or not, which is based on either (a) the @flow pragma in the
docblock of the file of (b) the `all` configuration, provided via
command line or .flowconfig.

This commit parses the @flow (or @noflow) pragma from the first comment
in the source file. Directives are allowed to appear before the comment.

* WIP: add tests for explicit type arguments

This commit includes tests which have unexpected output, but will change
to the expected output as later commits add parsing support for various
features.

* Parse type arguments in new expressions

* Parse type arguments in call expressions

* Parse optional call expressions with explicit type args

* Add explicit type arguments to babel-types

Flow calls these typeArguments instead of typeParameters, which clearly
separates formal/actual parameters, and mirrors the existing arguments
key.

The existing definitions to support TypeScript also included Flow's
TypeParameterInstantiation node type, which I've moved to the the new
field.

* Add support for explicit type arguments to babel-generator

* Add test for explicit type args to transform-flow-strip-types plugin

* Oops. Forgot to regenerate the babel-types README.

* Fix Flow parser shouldParseTypes() function

I was looking at `options.all`, but the correct property ws
`options.flowAll`. Oops!

* Remove typeapp_call from whitelist of expected failures

Now that Babylon parses this syntax extension, we can remove the
typeapp_call tests from the list of expected differences.

Note that I am using the `flowAll` option, mirroring the behavior of the
Flow tests, which assume types without requiring the `@flow` pragma.

* Use Babylon plugin options instead of parser options

* Parse optional call expressions type arguments unambiguously

341bdab90c Update decorators parsing (#7719)
* Update decorators parsing

This commit introduces three changes:
1) Class properties can be decorated
2) Decorators can contain arbitrary expressions, using @(...)
3) The Decorator node type has a new property, "arguments". This
    makes it possible do distinguish @dec() and @(dec()), which have
    different behaviors because @(dec()) is equivalent to @(dec())().

* Rename Decorator#expression to Decorator#callee

* Add test for @dec()()
