I've done some mostly trivial FORTH development [^0] and love it! That being said... there's absolutely zero guard rails. You'll find just as many, if not more segfaults as you would in C and there's no concepts of types really.

GForth is pretty good, the docs and tutorial are a great way to get started and the implementation is still actively developed.
