That would be ideal from my perspective, yes.

That’s something I’ve considered, yes. (Also, “latter”.)

No, it’s a Common Lisp thing that I picked up from the SXEmacs folk, and
that I find helpful and clear. (In CL it’s a macro that throws an error at
read time if the following symbol doesn’t have a function definition.)

This is unclear to me; are you asking me to resubmit the patch for this
reason?

Ah, yes, they should. I’ll resubmit the patch on that basis.

Meh, part of the cascade is at compile time, part at run time, and the
latter is only two deep. One more level and I would agree with you.
