SPUG: It gaugtht bettuh...

[Dyck, David]

It's been a while since I read
   http://perldoc.perl.org/perlref.html#Function-Templates

Did you see this note at the bottom:
   CAVEAT: Aliasing does not work correctly with closures. If you try to alias lexical variables from an inner subroutine or eval, the aliasing will only be visible within that inner sub, and will not affect the outer subroutine where the variables are declared. This bizarre behavior is subject to change.

OK, it looks like this list isn't quite dead yet... :-)

I've been using perl since sometime back in the 90's.

I ended up using it in an embedded linux system about 10 years ago
to replace a guile based scripting engine - That's one ugly M...

I used mod Event to create a pure event system to handle bunches of
serial IO and timer events. Worked/works great. Perl is a quite
a CPU big, but still compares well with other dynamic languages.

Seems that Python has taken over from Perl these days. I never liked
Python - using indention as fundamental element of syntax is obnoxious - IMHO.

I suppose Perl's goofy syntax make people cringe - I find it a rather
charming idiosyncrasy myself :-)

Question - Perl's anonymous functions seem to operate perfectly well
as closures - they capture the referenced environment properly and
free it when they themselves are no longer referenced. The guile
folks disputed that me those many years ago. Thoughts?
