Further reduced shows neither constructor nor delegate is required.

struct Struct4841(alias pred)
{
    void unused_func();
}

void bug4841a() {
   int w;
   Struct4841!(  w ) m;   
}

void bug4841b() {
   bug4841a();
}

----------------
The unused function is required only because it makes Struct4841 into a nested
struct.
I think it is because moving a templated nested struct changes its type - the
enclosing function is part of the mangled name, or something like that. It
can't trivially be moved around.
