I must not use Perl.
Perl is the mind-killer.
Perl is the little-death that brings total obliteration.
I will face my script.
I will permit it to run over me and through me.
And when it has finished I will turn on the debugger to trace its stack.
Where the Perl has gone there will be nothing.
Only I will remain.
