22:07:46Bikelike if you have nil in source code it will actually be a bir:constant with constant-value nil
22:08:02Bikealso i remembered the actual problem: if you copy (lambda (x) (lambda () x)) you need to copy the inner function since the variable is copied
22:08:12Bikebut if you copy (lambda () (lambda (y) y)) you don't need to copy the inner function
22:08:23Bikei guess i can probably finagle this without doing PCV though
22:10:54karloszBike: what are you using a function copier for, exactly?
