* 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
Co-Authored-By: Nicolò Ribaudo <nicolo.ribaudo@gmail.com>
* improved recordAndTuple generator error message, added tests for invalid,missing options
* updated error messages for invalid parser syntaxType option
