I did a little less digging and a little more thinking:

 >>> Direct3D.Mesh.FromFile.__overloads__[(str, Direct3D.MeshFlags, 
Direct3D.Device, 
clr.GetClrType(Direct3D.ExtendedMaterial).MakeArrayType().MakeByRefType())]
<built-in function FromFile>

Yay! Somewhat insane, but yay.

show him your sword.
When you meet a man who is not a poet,
do not show him your poem.
