in reply to Learning Perl Online

Many colleges and universities have quite decent Perl intro courses on line. Search for perl and .edu and pick one or more that suit your style.

You'll also find the Tutorials here useful for many cases of "a thing at a time" and, as LanX noted, simple participation in the Monastery can be an invaluable part of your learning.

[Eily]: hum, tied scalar, generates a new array when derefed ? :D
[Corion]: choroba: Ah, when doing a shallow copy, I prefer [ @$var ] - I think \@$var might return the same reference instead of a reference to a fresh copy
[Corion]: perl -wle "my $ar = [1,2,3]; my $br=\@$ar; print qq($ar / $br)" confirms this to me
[karlgoethebier]: "discovered" this to sum an array: perl -E 'say scalar map {1 .. $_} (1..3);'
[Corion]: karlgoethebier: Hahaha :)
