That's possible.

But I think the performance hit could be avoided almost entirely. Make
non-debug and debug versions of "semis" and "docol". On startup
construct the "words" table, while building select the non-debug
versions, unless some magic diagnostic switch is on. "next" or
"enterforth" may still need a test.

Maybe the switch to debug table could even happen during execution by
user command.
