Re: Perl: last evaluated value as a returned value for a subroutine. See insideby LanX (Chancellor)

EDIT: now I get it, the sub returns the evaluation from the unless-condition in the first line.
... WTF ...
You like obfuscation, don't you?

sure if you set $R to anything false ( EDIT:... it will start from new, otherwise it will print the new value.)
if you wanna avoid that anyone ever unintentionally changes $R, then put the whole closure construct into braces and $R is out of scope for any other code.
