Without Visual D (or to be more precise: without the mago debugger 
extension that comes with Visual D), you are rather limited when 
debugging D code.

It might work to use the mangled name, e.g. _D3mod4namei. You can find 
the exact speelling in the disassembly of an access to the variable.

An alternative might be to use extern(C) when declaring the variable.
