Recently Kenji mentioned that the following works:

-----
struct X(alias int x)
{
}

void main()
{
    int i;
    alias X!i IVal;  // ok

    float f;
    alias X!f FVal;  // fail
}
-----

Even if this is allowed by the current syntax rules, it is largely an
undocumented feature (compiler implementers could easily miss this feature as
well). It should be properly documented.
