--- Comment #3 from Basile-z <b2.temp at gmx.com> ---
I like the idea but i see an ambiguity:

---
int call(alias fun)()
{
    return fun();
}

int call(int value)()
{
    return value+1;
}

void main()
{
    call!{ return 0; }();
}
---

which overload is called ? The one that will doe CTFE and then call!0 or the
other ?
