How do you implement da_is_a_slice_of_a()?
Indeed, for that to work you'd still need to handle this case specially.
My bad for not catching that.
Personally, I think it'd be much cleaner to go with some kind of magic
function than trying to match the condition against a predefined
pattern. Something like da.isSliceOf(a), which could do the usual
pointer thing at runtime and call some sort of CTFE intrinsic at
compile-time.
That doesn't help when most code does not use this today. I.e. one of the
main benefits of ctfe is that you don't *have* to write special code.
