Improve swc_ecma_trnasforms (#127)
# swc_ecma_ast - Add PrivateName to Expr # swc_ecma_parser - Fix parsing of private name # swc_ecma_transforms ## Hygiene - It correctly tracks `BindingIdentifer` / `IdentifierReference` - Preserve `IdentiferReference` if it conflicts with a `BindingIdentifier` ## Block scoping - It correctly tracks `BindingIdentifer` / `IdentifierReference` ## Fixer - It removes useless parens. - It removes useless `IdentiferReference`s in comma expressions. ## Classes properties - public prooperty - private property ## Class decorators - implemented
