That is easy, we have things like
error "makeSketch: constant polynomial"
That is, include function name as part of error message.
We should, maybe, more often use the two argument error function.

Hmm, have you used them?
Oh, true, I haven't.
Documentation say "callable from the system interpreter". 'error' is
built into Spad compiler...
Wow! I learnt something new. As I understand it, there are two
error: String -> Exit
functions, one builtin and one from ErrorFunctions. I wonder why you say
that calling
error("blah")$ErrorFunctions
in SPAD code might not work. The only strange calls I see are
throwPatternMsg(s, []$(List String))$Lisp
and
"exit" pretend Exit
but are they really problematic?
OK the answer to the above is not soo important to me, but I think Greg
is right that the builtin 'error' should automatically show the function
name in which it is called. Doesn't the compiler have all this information?
Such an improvement would really be great.
