minimize output of rte-to-dfa
We have made no attempts to minimize the DFA which is produced.
For example the image shown in section Debugging is not
minimized. States 2, 4 and 5 can be combined into a single state, and
also states 1 and 3 can be combined. If states 1 and 3 are combined
the labels 0 -> 3 and 0 -> 1 can be unioned to the type
(not String) which
will improve run-time performance.
(or Long (and (not Long) (not String))) = (not String)
