Ah, I see!  Sorry for missing that.  I don't see a reason why we cannot support that, but I wasn't really considering it.  In general, this attribute is a compiler hint for some C standard library stuff in glibc.

I've been playing with it a few hours now, and it seems that GCC ONLY complains about the attribute parameter being in range (same error for the type of the parameter as well!), so we DO a bit extra SEMA here, though I think that is correct.  I'll dig into this a bit more and see if I can get the template return type working correctly.
