Yes, just try it – and see what happens with Data::Dumper or any of its ilk. (Also nice to use strictures and warnings!) 

>perl -wMstrict -le
"use Data::Dumper;
 my %hash = qw(a 1  b 2  c 3  d 4);
 my_function([keys %hash]);
 sub my_function {
   my $arr_ref = shift;
   print Dumper $arr_ref;
   }
"
$VAR1 = [
          'c',
          'a',
          'b',
          'd'
        ];
