in reply to Schwartzian Transfrom using a subroutine

I am getting the original sorting of the list.

Because your sub doesn't return the transformed string; it returns the result of the the last transform. Change that to:

sub transform{ my $string = shift; $string =~ tr/A-Z/a-z/;#kleinschreibung $string =~ tr/a-z//cd; $string; }

(As an aside; are you aware that for my $word (@output){say $word;} is more easily written as say for @output?)

    They are not the same:

    $ perl -E'my @x = qw/one two three/; for my $x ( @x ) { say $x }' one two three $ perl -E'my @x = qw/one two three/; say @x' onetwothree
      perl -E'my @x = qw/one two three/; say @x'

      You missed something...
