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.

By the way, it seems it does not support implicit type conversions.

For that I think I'd like this enhancement to work:

-----
struct X(alias T x, T : int)
{
}

void main()
{
    short i;
    alias X!i IVal;
}
