This *should* actually work. What type are those variables?
struct MouseKeyEvent {}

I actually don't know. The docs do say that function pointers
work differently - they match `is(typeof(f) == return)` but it

Yes, it's possible. For example:

It'd be nice if we could at least get the arity of a template,
then perhaps speculatively instantiate it and reflect on the
eponymous function then.

context. So that `a` variable might be changed somewhere else so
compile time can't read or write it.

Slicing never allocates memory. reserve extends
