Subject: [ruby-core:31679] [Backport #3680] Splatting calls to_ary instead of to_a in some cases

Issue #3680 has been updated by Run Paint Run Run.


I addressed this as a footnote of http://ruby.runpaint.org/variables :

<<Note that :to_ary is sent rather than the :to_a used by the splat operator. In the former case, the programmer did not directly request that conversion take place so the message for implicit conversion is sent; in the latter, his use of the splat operator constitutes an explicit conversion, so the more liberal protocol is followed.>>

So, in your example #to_a is sent when the splat operator is used explicitly; #to_ary when it is used implicitly.
