Bug #10699: m(*a, **b) doesn't recognize integer options.

It seems a method defined as m(*a, **b) doesn't recognize integer options.

% ./ruby -v -e '
def m(*a, **b)
  p [a, b]
end
m(1, 2 => 3)
m(1, :foo => 3)
'
ruby 2.3.0dev (2015-01-06 trunk 49159) [x86_64-linux]
[[1, {2=>3}], {}]
[[1], {:foo=>3}]

I think the result should be follows.

[[1], {2=>3}]
[[1], {:foo=>3}]

I found this problem by https://github.com/ruby/ruby/pull/808

[sawa (Tsuyoshi Sawada)]

I thought that was a feature. I proposed to extend the use of double splat, and a patch has already been provided by Nobu in #10118.

[nobu (Nobuyoshi Nakada)]

#10118 is only for splat, not rest keywords argument.

I didn't know this keyword arguments behavior.

Hm. I'm not sure the current behavior is good or not.

Anyway open3 has the problem since Ruby 2.1 and I don't expect Ruby 2.1 changes the keyword arguments behavior.
So I committed r49173 to fix open3 and it should be backportable.

Thank you akr san for your consideration about backports.
I'll fill Backport field with 2.1: REQUIRED only for r49173.
