until then, you could still bribe your unix sysadmins to   alias perl='perl -Mstrict'   globally.

Anybody can turn it of with   alias/unalias   and it doesn't affect shebangs anyway, so old code will still work, unless calling perl without a path to it.

Of course, to be really mean, you could put a wrapper around   /usr/bin/perl   too...
