From: Shyouhei Urabe Date: 2009-03-09T03:11:37+09:00 Subject: [ruby-core:22750] [Feature #1256] Add constant TAILRECURSION to let a program recognize if tail recursion optimization is implemented Issue #1256 has been updated by Shyouhei Urabe. I'm curious, how you can be happy if you detect your VM supports tail-call optimization or not (from your script)? I think you have to write without tail-calls anyway for compatibilities with those no-tail-call enironment. ---------------------------------------- http://redmine.ruby-lang.org/issues/show/1256 ---------------------------------------- http://redmine.ruby-lang.org
