Beschreibung

There are certain locations where arrow functions don't parse

var x = window.foo || () => {}

In these instances, it would be nice if users could get a better error message as to avoid issues like #25897.

Ideally this should not be an invasive change.

  • The change should be limited in scope.
  • The parser should continue erroring in those locations.
  • The change must not introduce change how existing valid code is parsed.
