Probably not without some `Devel::` module. Try this:

    perl -e'print ref \&foo; \&foo->()'

So `\&foo` is valid even before `foo` is defined (or indeed
declared), which means you need something that will peek at
flags in structs deep in the bowels of perl in order to answer
your question.

It isnât, but the subs in SDL::OpenGL::Constants should have the
right prototype (ie. `()`, same as constant.pm uses) in the first
place. Flick a bug report to the author.
