* fix: strip type imports used in Enums and object types
* chore: update failing snapshot
* docs: correct TSPropertySignature comment
* fix: enum value should be considered a reference
* chore: add tests for TSPropertySignature and TSEnumMember
* Refactor parsing object members
* Ensure decorators on rest don’t swallow decorators silently
* Use hasPrecedingLineBreak
* Add test for async with linebreak
* Update flow whitelist
* preset-env: minimally supporting version
This changes the "does browser support X" algorithm to "lowest version such that all higher versions support it".
Eg, given `{ chrome70: true, chrome60: false, chrome50: true }`, the lowest version is chrome70, not chrome50.
This is done to remove Tagged Template Literal support from Safari, which introduced a bug in Safari 12 but correctly implemented the feature in Safari 11-9.
* Add tests
* Fix tests
* Fix comment
Likely because of implicit `equals` (ie, Safari 12 support implies iOS Safari 12), the versions in the `res` hash are not always sorted in version order.
Doing a semver sort reveals some builtins have actually been supported a little longer than we thought!
In https://github.com/babel/babel/issues/9511 (and #9495 is another symptom), @PavelKastornyy reported a node crash becaue the JavaScript heap run out of memory. The problem was that their code was adding enumerable properties to `Object.prototype`: it is something that shouldn't be done, but Babel shouldn't make node crash if someone adds them.
I reduced down the problem to `for...in` loops in `@babel/traverse` that grew the memory consumption exponentially because of that unexpected properties.
* Introduce scope tracking

* Remove constructor-super check from transform as it is now in parser
* Correctly handle class properties and class scope
* Fix duplicate name check
* Convert scope identifier storage to array
* Enter a new scope in typescript module blocks
* Add test for duplicate declaration
* Rename error for duplicate exports
* Treat class declarations as lexical declaration
* Update whitelist
* Add tests
* Fix scope tracking for function declarations
* Migrate try-catch duplicate error
* Fix test
* More tests
* One more test
* Make scope a separate class and fix review comments
* Do not allow new.target in top scope arrow function
* Correctly enter new scope for declare module and treat type aliases as lexical declarations

When set to `true` we create `ParenthesizedExpression` nodes instead of
setting `extra.parenthesized`.

* Use | null | undefined instead of any, make Flow type nullable
* Also change flow types of generated src
chokidar 2.0.3 pulled in an older version of braces which is vulnerable to https://www.npmjs.com/advisories/786, this upgrades chokidar up a patch version where its dependencies have been updated resolving this vulnerability.
* Migrate try-catch duplicate error
* Remove exception for functions and let in the same scope
* Migrate duplicate bindings tests to traverse
* Add test for subscope and let/const
* Add more test cases
