My understanding is that symbols with double underscore or underscore
followed by an uppercase letter are reserved, while _something
symbols are ok if they are not exported and that is actually
what we are doing. I prefer _perl because it is readily apparent
that the interface is private. Besides ANSI C allows a compiler to
consider only the first 6 chars in identifiers: we don't want to go
that way.
