Did any language implementers out there ever notice that Wirth does
not define the syntax of a "comment" in the "Syntax of Modula-2" in
the back of PIM2. They don't appear in the railroad diagrams, either.
He mentions them on page 16 (3rd edition), but even there
he doesn't mention that they can be nested.  I realized this after
playing with EBNF for some language stuff and found it very
difficult to describe "arbitrary sequences of characters" in EBNF.

My question is: "Was it an oversight or was it intentionally avoided?"

PS. Don't bother looking in the index, they aren't mentioned there.
