Good story, we've all been thru this once. =)
Just a hint

well you could set up an alias psw=perl -Mstrict -Mwarnings if you think that you'd really go to declare variables.
IIRC there was also a possibility to globally require a a piece of Perl code whenever your installation runs.

or see perlrun#PERL5OPT: "Switches in this variable are treated as if they were on every Perl command line."
though you might prefer to avoid strict vars in one-liners
comming back to your original case
