Let's not redefine the language just because there are bugs to fix.
Surely it is better to concentrate first on fixing the bugs so that
we can then more fairly judge whether the feature is useful enough
to justify its existence.

:One restriction might be to disallow various op-codes within the reg-ex
:assertion.  Namely user-function calls, reg-ex's, and most OS or IO
:operations.

That seems quite unreasonable. Why do you _want_ to restrict someone
from calling isKeyword($1) within the regexp, which will then read
the keyword patterns from a file and check $1 against those patterns
using regexps? It seems like an entirely reasonable and useful thing
to do.
