Typedefs in function scope don't get fully mangled with scope information.  As
a result, the following code won't link:
-------------------- test.d
struct Struct(T)
{
    T value;
}
void main()
{
    {
        typedef int Number = 1;
        Struct!Number s;
        pragma(msg, "1: ", typeof(s).mangleof);
    }
    {
        typedef real Number = 2;
        Struct!Number s;
        pragma(msg, "2: ", typeof(s).mangleof);
    }
}
--------------------

On Linux and FreeBSD:
--------------------
1: S4test20__T6StructTT6NumberZ6Struct
2: S4test20__T6StructTT6NumberZ6Struct
test.o(.rodata+0x18): multiple definition of `_Dmain6Number6__initZ'
test.o(.rodata+0x14): first defined here
--------------------

On Windows:
--------------------
1: S4test20__T6StructTT6NumberZ6Struct
2: S4test20__T6StructTT6NumberZ6Struct
