Yes. #!r6rs and #!whatever are not comments. In some systems, #!whatever
for some value of whatever might have some effect on the reading of
subsequent forms, which one would not expect a comment to do. In other
systems, the same #!whatever might cause a read-time error, which one
would expect a comment not to do.
