Never mind, it seems that there's been work done in this area

I'm glad this works, and sorry that I hadn't read the mail where you said you'd
figured it out.

Try adding .MakeByRefType() to what you have:
>>> Direct3D.Mesh.FromFile.__overloads__[(str, Direct3D.MeshFlags,
>>> Direct3D.Device,
>>> clr.GetClrType(Direct3D.ExtendedMaterial).MakeArrayType().MakeByRefType())]
Another possibility would be to display the elements of __overloads__
explicitly

you won't have to deal with the

I didn't know about the array type trick but I'm still having some trouble.
This is

The array_EffectInstance is EffectInstance[] and to get that type, you can do:
clr.GetClrType(Direct3D.X.EffectInstance).MakeArrayType()
For example:
>>> clr.GetClrType(System.Collections.Hashtable).MakeArrayType()
System.Collections.Hashtable[]
Hope this helps.
