Yes, that's what I meant.

Perhaps it's just me that I envision hierachies of error classes.

Not being able to catch  ARITH and all subclasses like a "ARITH MATRIX"
with the same clause - just because the latter has list-meta-syntax that
needs to be taken care of - feels just wrong to me.

If we specified the pattern to be applied only to [lindex $errorCode 0]
or [join $errorCode], that would also solve the problem.

Otherwise we'd have to discourage use of spaces and all other
list-special characters in user defined errorcodes.
