Thank you, both. It still rules out an address at "compile time" in 
general. For example, we cannot use such an address when instantiating a 
template, or static array length, etc.

And if I understand it correctly, there must be a pointer *variable* for 
the linker to initialize. Fine then: That's how this usage works for C 
but not for D. :)

Thank you,
