Hi Monks !

I've got impossible error from Perl:
"Can't use string ("string") as a HASH ref while "strict refs" in use at C:\... line 1190"

What the heck should be this error ?

I searched the Web, and here what I got:
code 1:

#!/usr/bin/perl -w
use strict;
sub showArray(\@)
  {
  my(@arr) = @{(shift)};
  my($temp);
  foreach $temp (@arr) { print "$temp\n"; }
  }
sub higherLevel(\@)
  {
  my(@arr) = @{(shift)};
  showArray(@arr);

  }

my(@arr) = ("one","two","three");
higherLevel(@arr);

Code 2:

#!/usr/bin/perl -w
use strict;
sub higherLevel(\@)
  {
  my(@arr) = @{(shift)};
  showArray(@arr);
  }
sub showArray(\@)
  {
  my(@arr) = @{(shift)};
  my($temp);
  foreach $temp (@arr) { print "$temp\n"; }
  }
my(@arr) = ("one","two","three");
higherLevel(@arr);

The first code went great, but the second returned the previous error !
I do not understand, the two sections are the same !!!
What the heck is going on?
Mosh.
