That doesn't help. foo.func() is still ambiguous. With this proposal, you  
have hijacked the meaning of namespace lookup. When I say x.y.z, it  
doesn't just mean look for symbol z in module x/y.d, it can also mean to  
look for symbol z in C++ namespace x::y. This was not the case with C  
binding, which continued to use D modules for symbol lookup.

Consider that a boatload of C++ code is named std::something. Now,  
std.string has an ambiguous meaning wherever it is used!
