Named events really should be expressed with PEIdent
...
objects in the pform,
Handle named events within the mix of net events
and edges. As a unified lot they get caught together.
wait statements are broken into more complex statements
that include a conditional.
Do not generate NetPEvent or NetNEvent objects in
elaboration. NetEvent, NetEvWait and NetEvProbe
take over those functions in the netlist.

I now generate the scopes and notice the parameters
in a separate pass over the pform. Once the scopes
are generated, I can process overrides and evalutate
paremeters before elaboration begins.
