I hadn’t seen this commit series until now but I like it!  :-)

I’ve always thought that smobs-as-structs would be a good thing, not
only to reduce code size and simplify procedure dispatch, but also to
remove arbitrary limits like on the number of smob types.

Keep up!

Thanks,
Ludo’, amazed by the pace at which things have been falling into place
over the last couple of weeks!

Yes, all this is possible. However I ran into some snags, and I wanted
to wait until we had bytecode trampolines for subrs as Bruno Haible
suggested before proceding further.

I just had a lot of branches that needed eval.scm to work :)

Cheers,

Andy
