> Most modern FORTH don't have SMUDGE any more, which has been replaced by HIDE and REVEAL. I think, the modern Forths (i.e. since 1994 ANS Forth standard) need neither HIDE nor REVEAL as these are made superflous by RECURSE. Other edge cases could be handled using a mechanism like DEFER [1] (which can be implemented in terms of ANS Standard words). Just looking through the manual, even the modern Gforth has something like RECURSIVE [2] which is just a differently named implementation of REVEAL.
