[ruby-core:95408] [Ruby master Bug#14176] Unclear error message when calling method with keyword arguments

Issue #14176 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Closed

With the separation of keyword arguments and positional arguments in #14183, I think this can be closed.

Bug #14176: Unclear error message when calling method with keyword arguments 
https://bugs.ruby-lang.org/issues/14176#change-82151

* Author: vfonic (Viktor Fonic)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-darwin17]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
I (wrongly) created a method with the following signature:

def asd(first, options: {}); end

(notice that options is a keyword argument)

I called the method this way:

asd(arg, options)

And got the following misleading error:
ArgumentError: wrong number of arguments (given 2, expected 1)

It took me some time to realize that the options argument is a keyword argument:
> method(:asd)
Object#asd(first, ?)

It would be much more helpful if the error would mention this:
ArgumentError: wrong number of arguments (given 2, expected 1 and 1 keyword argument: options)

Thanks!
