Perl6::Rules is not your run-of-the-mill CPAN module and is not recommended for production use; it's an exploratory module, right at the leading edge, pushing Perl 5 beyond its capabilities. This module is used mainly by Perl 6 language designers to gain some real-world experience with the new Perl 6 Rules in order to improve and debug their specification. I assume use strict was turned off because this module, in pushing Perl 5 way beyond its normal boundaries, uncovered some bugs or limitations with use strict.

It is so well-known in the Perl community that only Neanderthals (note to DrHyde: davorg's description, not mine) make comments like use strict is stupid or even, gasp, use strict is gay, that there are at least two running jokes on this theme, namely use strict is gay and use strict with pride. Knowing TheDamian's sense of humour (he has the dubious distinction of being the inventor of the Acme namespace), I'm sure he was just making a joke when he put in the change log "removed stupid use strict ;-)".
