in reply to Rename unreliable on Windows

Script runs fine for me; no crashes. Windows 2008 R2, Perl 5.12.4.

I suspect you're triggering some sort of race condition in Windows' file locking, but even if I removed the print to STDOUT to try to speed things up, I wasn't able to trigger it. Sleeping for a few microseconds before calling rename might help.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
