I disagree - I have used (and cursed) trace / debug "facilities" in
several
commercial languages, and aside from the awkward way of displaying
strings, the
Euphoria trace is the most usable of all.

I agree wholeheartedly with the following, however:

Not only that, but with the present situation, you lose the "safety" of
Euphoria's automatic type checking.  Your suggested structure would
restore
type checking, preventing assignments like age = "twwnty" or salary =
"Fred".
A much needed improvement, plus it fits into the current way of doing
these
things as implemented in several other languages. Also, it's clear and
understandable.
