      Allow trailing commas in function parameter lists · 1ac09655
      jwolfe authored
      Add a flag harmony_trailing_commas_in_parameters that allows trailing
      commas in function parameter declaration lists and function call
      parameter lists. Trailing commas are allowed in parenthetical lists like
      `(a, b, c,)` only if the next token is `=>`, thereby making it an arrow
      function declaration. Only 1 trailing comma is allowed, not `(a,,)`. A
      trailing comma must follow a non-rest parameter, so `(,)` and `(...a,)`
      are still SyntaxErrors. However, a trailing comma is allowed after a
      spread parameter, e.g. `a(...b,);`.
      
      Add parser tests for all of the above.
