in reply to Error on comment line

Maybe this comment is not a comment indeed. It may be inside a larger quote construct that does interpolation, like

my $a = " # this is a comment, but not really (with $interpolation) $a = 3 "; print $a
printf <<PERL, "not"; for (@html) { pretty_print($_) } # a comment is %s always a $comment # subtler because of here-docs PERL

Any of these would trigger similar warnings, due to the unitialized contents in $interpolation, $a and $comment.

    Being a runtime warning, the line number in the message would be the line number of the start of the statement. In the first snippet, the warning would appear to originate from my $a = ", not the "comment" line.
