Subject: [ruby-core:58551] [ruby-trunk - Bug #8418] when all params are	optional, named arg hash maps to the first available param


Issue #8418 has been updated by rits (First Last).


but isn't it good to have correspondence between keyword args and keyword hash?

when keyword args are used explicitly at invocation (foo a: 1, foo **hash) but the method signature does not use keyword params, it seems natural to bind the resulting hash to the last possible param, not the first

irb(main):028:0> def foo(arg = 1, options = {}); {arg: arg, options: options}; end; foo(a: 1)
=> {:arg=>{:a=>1}, :options=>{}}

since positional args can't follow the named hash, perhaps the named hash should map to the last possible param?
