extern(C++, ns)

[Danni Coy via Digitalmars-d]

D generally doesn't allow shadowing of names inside inner scopes.

int x;
for (int i=0; i<max; i++) { int x = i*2-1; }

works in a lot of languages but not D.

int x;
extern (C) int x;

doesn't work.

having

int x;
extern (C++,ns) int x;

work
might be useful but to me seems inconsistent with the rest of D.

Using sub modules to deal with this seems very much more consistent
with the rest of the design of D.
