Re^2: hash from sub directly into foreach loop

sorry for all the confusion about the typo.

But thnx for the %{ { &testa } } that does the trick!
I guess it might be very usefull to study the perlsub (how do you guys make this a link, where is it documented, I've search the docs already a couple of times ?)!!

You're welcome, but I did say `%{ { testa() } }`, not `%{ { &testa } }`. Your specific example code doesn't bump into the difference, but there is a difference. It's just good to be in the habit of using the `subroutine()` method of calling subs, instead of the Perl4-ish (and sometimes confusing) `&subroutine` method. As for how to link to perlsub, see About the PerlMonks FAQ, and specifically, What shortcuts can I use for linking to other information?. ...but first read perlsub; that's a much more important step toward your understanding Perl.
