Hope this helps.

[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 :)
