As I remember, it wasn't so immediately apparent what the problem was,
since the failure didn't occur til a little ways after the + happened.
And the symptom was that the program crashed without much clue about
what had happened.  Of course fancy debugging tools would have made it
easier to trace and fix the problem, and it's not inherent in Forth that
the implementation I used didn't happen to have them.  Looking at the
code now, its factoring doesn't seem too bad, though maybe it could be
better.

Anyway, if a type-checked language lets me write a page full of code and
fix the compile-time errors to usually get working program, while the
typeless counterpart makes me stop what I'm doing after basically every
single line to check for problems the type checker would have caught
automatically, I'd say the type checker has made itself worthwhile.
