yes. the semantics were enhanced to a superset of those in "sim" common.
unfortunately rtl trees seem to be given a fixed operational semantics
in terms of the C code they generate. there is, from my limited
understanding, no other place in which an application is *able* to alter
interpretation of the (delay...) rtl node, or its sub-nodes, without
replacing parts of "the" rtl-evaluator.
I certainly would have liked to put all these changes in *-sid.scm, I
just didn't find any practical way to do so. any suggestions?
