auto add(A, B)(A x, B y)
{
    return x + y;
}

void main()
{
    alias curry!(add, 5) add5;
    assert(add5(6) == 11);
}

test.d(57): Error: template std.functional.curry!(add,5).curry(T) if
(is(typeof(fun(arg,T.init)))) does not match any fu
nction template declaration
test.d(57): Error: template std.functional.curry!(add,5).curry(T) if
(is(typeof(fun(arg,T.init)))) cannot deduce templat
e function from argument types !()(int)

The problem is with the constraint for curry(T)(T arg2). Remove the constraint
to workaround.
