Oh. That's gotta be a typo, and as such I read right over it without even consciously noticing it. Imagine what happens when your code is called by a program that stored some helper :: whatever ; in the most recent NULLLAM... like something that eats stuff from the stack... All hell's going to break loose. I've never done that obviously, which explains why I never ran into those problems with last stack disabled.
But knowing that TRUE, FALSE, NOP (can push with 'NOP in one command) and friends can safely be used is useful info, thanks. I might use that in the future in place of NULLLAM - but NULLAM itself still has a use: if you use that name for your local variables, there's an equivalent of 2GETEVAL for the first local variable: an unquoted NULLLAM. It might not be quite as fast as 1GETLAM EVAL (not tested, though I'm expecting things to be like that because this is recalling by name instead of by index), but it's shorter, so I prefer placing local-variable-stored subroutines in the first two variables to be able to use that trick.
