I don't. A define a procedural language as one in which all modules have
a parent-child relationship with each other. I also don't classify languages
by implementation details... for example, SmallTalk uses messages to pass
data between procedures, but since they generally have a parent-child
relationship (one calls the other) they're still procedures. Icon uses
a stack to pass a stream of data between concurrently executing modules.
They have a source/drain relationship. It's non-procedural.
