Well, this is what I meant by measures.  I guess it would be easy to
have an "other" category at a later date.  But the Haar measure on the
real line is a nice object, and discrete has a good definition too.
Having this distinction would at least be helpful in starting out with
such classes.

That is a very good idea.  We even have (or should have soon) a
symbolic erf for the normal distribution, to start things off...
