      Why? I would have expected that using the foreach $string acutally is assigned to whatever is the element of the array but aparently this is not the case.

Turn on strict and warnings and you'll see why.

use warnings; use strict; my $sref = \$string; foreach $string ( @array_of_strings ) { print $$sref; } $ perl sref_o.pl Global symbol "$string" requires explicit package name at sref_o.pl li +ne 4. Global symbol "$string" requires explicit package name at sref_o.pl li +ne 5. Global symbol "@array_of_strings" requires explicit package name at sr +ef_o.pl line 5. Execution of sref_o.pl aborted due to compilation errors.
