I guess it's just an artifact of handling line continuations within
expressions where a different rule is applied. For compilation
purposes both the newlines within expressions as well as the comments
are irrelevant. There are even two different token namely NEWLINE and
NL which are produced for newlines. NL and COMMENT will be ignored.
NEWLINE is relevant for the parser.
If it was a bug it has to violate a functional requirement. I can't
see which one.
