in thread Perl allows you to change the definition of false to make it true. (And vice versa.)

AFAIK, only true, false and undef. I thought perhaps "0 but true" might work (as that has special handling - it doesn't warn if used in numeric context) but no joy.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
