Bug #8993
closedRequest for clarification on method argument binding for keyword arguments
Description
=begin
I recently fixed keyword arguments in the JRuby interpreter, and I then found an example for which MRI and JRuby have different behavior:
def foo(a, b, c=1, *d, e, f:2, **g)
[a, b, c, d, e, f, g]
end
foo(1, 2, f:5)
MRI raises:
ArgumentError: wrong number of arguments (2 for 3+)
... whereas JRuby produces:
[1, 2, 1, [], {:f=>5}, 2, {}]
I implemented the behavior in JRuby to conform with MRI, but in this case, I think that JRuby's behavior is correct, based upon the discussion in #8040.
Is there a spec for this feature somewhere (aside from the RSpec specs that I submitted to the RubySpec project)? In #7529, Matz refers to "the spec" for this feature, but I don't know where or what that is.
