Just lately I have come to depend on Data::Dumper a lot, particularly as I'm developing in a web environment where running a debugger is not practical.

I've come to often quickly add the following into a block of code:

  {
    use Data::Dumper;
    print( Dumper( \%hashvariable ) );
  }

I put braces around just out of habit.

Note that I put the backslash in front of the hash reference, for some reason that results in a clearer-to-read output from Dumper than just Dumper( %hashvariable ).

When in a web environment (such as Mason) I use the following to dump my variables:

  {
    use Data::Dumper;
    $m->out( '<pre>' . Dumper( \%hashvariable ) . '</pre>' );
  }
