Oooh! So dirty! ;)
I've never used the intrinsics module (and Googled, but apparently didn't search
for the right thing), but does this do a global replace? E.g. if my module
imports some module that calls intrinsics.replace(str, phpstr), are all the uses
of str in my module then replaced with phpstr's?
