Description
m(&nil) {} というまちがったコードは
ruby -c でちゃんとエラーになるのに、
Ripper.sexp ではならないようです。
% cat z.rb
m(&nil) {}
% ruby -c z.rb
z.rb:1: both block arg and actual block given
% ruby -rripper -e 'p Ripper.sexp(STDIN.read)' < z.rb
[:program, [[:method_add_block, [:method_add_arg, [:fcall, [:@ident, "m", [1, 0]]], [:arg_paren, [:args_add_block, [], [:var_ref, [:@kw, "nil", [1, 3]]]]]], [:brace_block, nil, [[:void_stmt]]]]]]

This bug still occurs in the master branch. Attached is a patch that fixes the problem by overriding Ripper::SexpBuilder#on_method_add_block
. This isn't a very clean way to fix it, but I was not able to figure out a way to fix it by modifying parse.y
.

I'm overhauling ripper to multiplex the callback values and the parser union.
