Is it supposed to possible to mixin a constructor? The code below

A template mixin introduces a new scope. This is pretty annoying in some
cases. More often, it is convenient. Since the constructor is not in the
same scope as the class, it might be causing problems.
If you didn't introduce a new scope by default, it'd be easy enough to
add it in the template or around the mixin:
template MixMeIn()
{
int imInUrScope;
{
int imOuttaUrScope;
}
}
Additionally, the difference would be easily detectable, because symbol
collision would cause the code to fail to compile. Unless the mixin adds
a function overload and you pass the address of the overload set
somewhere, and now you're passing the wrong overload...which is an old
problem for D, aggravated by D's property syntax, and unlikely to be
fixed soon.
