I think it kinda does.

in C/C++, the following is valid declarations:

     typedef int foo;
     int(x); //OK, declares x as int
     foo(y); //OK, declares y as foo

in D, we get this:

     alias int bar;
     typedef int foo;
     int(x); // OK, declares x as int
     foo(y); // OK!!
     bar(z); // OK!!

     int main()
     {
         .y = 10; // ok
         .z = 20; // ok

         int(x); // OK, declares x as int
         foo(y); // Error!!
         bar(z); // Error!!

         return 0;
     }


why is foo(y) allowed at the global scope? and why is it disallowed at 
local scope?!!
