looks good, just the one comment about removing the FIXME comments.

The reason for the second FIXME was because TS was complaining when the __id__ was first. It said toCanonical always returned an __id__ so it was unnecessary to set one first. I couldn't figured out why my changes caused this to be a problem so I just moved __id__ to the end. I guess your changes fixed this if TS isn't complaining anymore.
