Subject: [ruby-core:31702] [Backport #3680] Splatting calls to_ary instead of to_a in some cases

Issue #3680 has been updated by Tomas Matousek.


I'm confused. You're saying that in 1.9.2+ splatting operators don't call respond_to?(:to_a/:to_ary)? Almost all other conversions do call respond_to? first before calling the method itself. E.g.:

class C
  def respond_to?(name)
    p name
    false
  end
end

String(C.new) rescue p $!
Array(C.new)

ruby 1.9.1p378 (2010-01-10 revision 26273) [i386-mingw32]
:to_s
#<TypeError: can't convert C into String>
:to_ary
:to_a

So why should splatting, which is essentially a conversion to an array, be any different?
