Thanks for quick response. I really forget to look into

Another option:

enum isFoo(T) = is(T == Foo!P, P...);

By using such an is-expression you get the parameters Foo was 
instantiated with as an added bonus.

struct Foo(T)
{
        T val;  
}

auto createAFoo(T)(string s)
if(is(T == Foo!P, P))
{
        return T(s.to!P);
}
