No. Constants aren't substitutions like C-preprocessor macros
are.
If you use
=>, it's left hand side will be
autoquoted if the left hand side looks like an identifier.
Barewords are valid identifiers, and that's what you have here.
So, either use a comma, preceed
ROTATE with the
(no-op) unary plus, put parens after
ROTATE,
or something else such that it isn't a bareword anymore.
Doing use inside a BEGIN is not
needed, as use itself happens at compile time.
