Our goal for Dylan is not to produce a research language, but to produce
a language which can be used to deliver commercial quality applications.
We've had to moderate reflective operations to achieve this goal.

I don't expect that we'll be going in this direction. We'd certainly encourage
anyone who wants to do research on extending Dylan in these directions, though.
