> Since we’re talking about this, there is an old maxim amongst FORTH programmers that if a single word’s definition takes more than a page, it’s just too dang long.   There are some solid reasons for that, namely the fact that forth is already hard enough to read as it is (and I’m speaking as a FAN of the language) and you generally need to keep the “internal stack state” in your head while writing a word since the stack contract is only at word boundaries (e.g. word is defined as tacking stack parameters foo and returning stack parameters bar).   Keeping the definitions short and sweet really helps to aid in comprehension.

I'll give that a shot shortly.
