Cool, thanks.

Sounds good.  At least, Rubinius community does not know any actual
case where WNA message is parsed.

You know, making parsing easy is not the purpose or the right way.
My concern is just about compatiblity.

Looks good to me.
It brings not only behavior consistency but also good refactoring
effect.

I noticed some minor issues below.

vm_insnhelper.c:

    +static inline VALUE
    +rb_arg_error_new(int argc, int min, int max) {
    +    const char *template = "wrong number of arguments (%d for %d..%d)";
    +    if (min == max) {
    +	template = "wrong number of arguments (%d for %d)";
    +    }
    +    else if (max == UNLIMITED_ARGUMENTS) {
    +	template = "wrong number of arguments (%d for %d+)";
    +    }
    +    return rb_exc_new3(rb_eArgError, rb_sprintf(template, argc, min, max));
    +}

It would be good to match the number of %d and actual arguments.


eval.c:

    -    if (i < argc) goto wrong_args;
    +    if (i < argc) rb_raise(rb_eArgError, "wrong arguments");

I guess this line can be removed, though this is not your fault.


test/ruby/test_arity.rb

    assert_equal "0 for 1",     err_mess{ "".sub!{} }

This assertion fails.  Did you mean "0 for 1..2" ?

So far, the remaining issues I know are better error message, and #5989.
