Subject: Tail recursion with 1.9

Hi,

I read in the first answer here http://stackoverflow.com/questions/824562/does-ruby-perform-tail-call-optimization that tail recursion is not on by default and is enabled by uncommenting a line in the source before compilation. Is this still true, and is there anyway to tell if it's on or not in a particular installation?


Regards,
Iain
