This is actually a compiler bug! I will check to make sure it's not
already filed, and file if it's not. However, I don't think the code
should work, it just shouldn't print e2ir.
}
Is there are a good reason for this being disallowed?
You'd expect `cast(void*)s == s.p`? That doesn't work for any type of p.
I was expecting it to work regardless of the type of p. I have an 8 byte
(on x86_64) struct which I want to reinterpret as a void*
You can do it with a slightly fancier (and more dangerous) cast:
`*cast(void**)&s`.
Yuk. Better than nothing though. Thanks :)
This is what reinterpret_cast from C++ does.
