Fusion

[David Feuer]

I'm still figuring this stuff out! Yes, I'd be glad to try to write
some of it up, to the extent that I understand it and in the hope that
someone who knows more will improve it. I am, however, hopeful that
you deep guru types will come up with a way to avoid the need for some
of the more intricate bits. Yes, I am glaring in the general direction
of the inliner.

If you did this, someone who follows in your footsteps wouldn't need to re-learn everything.  And maybe someone will say "oh, there's one pattern you have omitted, here it is".
