It's hard to edit the body of the module.

I was trying to fix some aspects of error handling, which covers many
predicates across multiple backends.  I kept losing my place and my
progress, by having to page over many unrelated (for the current task)
procedures and foreign code blocks.  Nothing that couldn't be overcome,
but smaller submodules would make it easier.
