Argument Forwarding without Parenthesis

[eric1234]

I see in #311 support was added for argument forwarding. I tend to be a minimalist so don't usually put parens on my method defs unless the compiler requires it. This is acceptable by Ruby but not by ruby_parser.

$ irb
irb(main):001:0> require "ruby_parser"
=> true
irb(main):002:0> RubyParserStuff::VERSION
=> "3.20.1"
irb(main):003:1* def foo ...
irb(main):004:0> end
=> :foo
irb(main):005:0" RubyParser.new.parse <<RUBY
irb(main):006:0" def foo(...)
irb(main):007:0" end
irb(main):008:0> RUBY
=> s(:defn, :foo, s(:args, s(:forward_args)), s(:nil))
irb(main):009:0" RubyParser.new.parse <<RUBY
irb(main):010:0" def foo ...
irb(main):011:0" end
irb(main):012:0> RUBY

good find. wanna take a whack at it?

[zenspider]

A: no, no you don't...

I think I have this fixed up.

[eric1234]

I apologize for ghosting you. I meant to respond but then got pulled off on some other things and more time than I meant ended up passing.

The answer is still largely the same. Looking over the change you made, my ignorance on Yacc makes this too far outside my wheelhouse. But regardless I should have responded earlier. The work (as well as some of your other work I use) is greatly appreciated.

No worries at all mate. This one was a doozy even for me.
