Re^2: I'm getting some weird error

Thank you! Yes, that works now. But I don't understand why mine didn't work. It was saying


printList was called.
Hey, I am from Italy! 1 2 3 4
Can't use string ("1") as a subroutine ref while "strict refs" in use

I wasn't trying to use "1" as a sub ref. What is that all about???

You called your subroutine, and then tried to call its result again, as a subroutine: `&$subref; # this calls the subroutine &$subref->(); # this calls the subroutine and tries to call the result + again, as a subroutine` [download] Using `&` is a bad idea in most cases.	[reply] [d/l] [select]

Perl offers two ways to dereference (most) datatypes. with the right sigil like `&$code_ref(ARGS)` with a deref arrow + bracket `$code_ref->(ARGS)` Same for hashes and arrays. You mixed both (and Corion explained what happend) See perlreftut and References quick reference for more.
