  Just look at it:

  msg = ' spacey string ';
  msg.replace(r'^\s+', '');
  msg.replace(r'\s+$', '');

  That’s clearly orders of magnitude easier to read than the Perl version.

    Oh wait, it has to be this:

    msg = ' spacey string ';
    msg = msg.replace(r'^\s+', '');
    msg = msg.replace(r'\s+$', '');

    Or possibly chain the methods.

    msg = ' spacey string ';
    msg = msg.replace(r'^\s+', '').replace(r'\s+$', '');

    Perl can’t hold a candle to any of that.

      In Python that can be written as:
      msg = msg.strip()

        Hey, but that's nearly impossible to write in Perl. Let me see:

        # in-place version
        sub strip { s/^\s+//; s/\s+$//; }
        # which would be used as
        strip($msg);

          That won’t quite work. Make it

          sub strip { $_[0] =~ s/^\s+//; $_[0] =~ s/\s+$//; }

          or maybe

          sub strip { s/^\s+//, s/\s+$// for $_[0] }

            use strict;
            use warnings;
            
            my $string = " This is the test ";
            
            sub trim {
                    my $a = $_[0];
                    $a = join(" ", split(" ", $a));
                    return $a;
            }
            
            my $nstring = trim($string);
            
            print "$string\n";
            print "$nstring\n";
            
            I don't think it takes every case...but it works with the "test" string.
