IMO Lisp is harder to implement than Forth, and LESS readable, butt MAYBE i fell into the same trap as others with Forth. hahaha

actually I think Lisp is easier to implement than Forth, buth is it really Forth if the internals aren’t discussed? (E.g. Word secondary, threaded code, etc)

Forth does not specify threaded code. Implementation is left to the implementor.

Internally Forth can be direct threaded code, indirect threaded code, byte code, sub-routine calls or optimized native code.
