There is a workaround:

template C ()                                                                   
{
    this (int i)
    {
    }
}

class A
{
    mixin C f;
    this ()
    {
    }
    alias __ctor = f.__ctor;
}

void main ()
{
    auto a = new A(3);
}

It seems that the __ctor alias works only if the symbol is already defined.
