Hi,
On my first attempt to create a templated class, I'm hitting an 
issue that I can't seem to resolve.

I've dustmite'd the code down to:

class Cache(O, K, F)
{
}


void main()
{
        class BasicObject
        {
        }

        BasicObject lookupBasicObject() {
        }

        Cache!(BasicObject, string, lookupBasicObject);
}


and I'm hitting the following error:

cache.d(23): Error: template instance Cache!(BasicObject, 
string, lookupBasicObject) does not match template declaration 
Cache(O, K, F)

Any help would be much appreciated in understanding what I am 
doing wrong.

Thanks.

Take care,
Fabrice.

By default template parameters are Types. lookupBasicObject is 
not.

change this `class Cache(O, K, F)` to `class Cache(O, K, alias F)`
and it should work.
