Well, I'd call it lexing (it's part of the tokenizer, not the parser). But
of course the line between lexing and parsing is rather arbitrary and
typically depends on the implementation.
For Ada, I would say that the contents of Section 2 are lexing, and
everything else is parsing. That was literally true in early versions of
Janus/Ada, including pragmas [they really were dealt with lexically]). For
Ada 95 and later, pragmas have gotten too complex and don't belong in
Section 2, but everything else there is lexical.
Getting back to the topic, since comments are in Section 2, they are clearly
lexical and not parsed. QED. :-) So talking about "parsing" them is
definitely nonsense. But since the rule in question would be purely lexical,
it certainly could have made sense.
Randy.
