You jump questions ;)
1) Procedure properties do work on programs. They just aren't
serialized to disk. But some serializations set properties on the
resulting procedure -- e.g. define*.
2) Programs do have properties -- program-properties, i think the
accessor is.
3) Should arity be accessed via procedure-properties? I think not.
Logically properties are cached values, not computed values, whereas
arity can be computed.
3.5) Should arity even be represented like that? The recent addition to
(ice-9 session), procedure-arguments, is another take on that
question.
4) For some reason I like numbered lists recently? Please take it as
some way of organizing my thoughts, it's not intended to be pedantic
;)

They still can.

We spoke of this on IRC, for those that weren't there. Actually, for
those that don't know: #guile is a friendly place. We actually have a
night shift going during the week, if you drop in between 21h and 24h
CET, people are likely hacking away :-)

I want to fix this soon.

Is this really the case? Can you make a test case?

Great, I'm looking forward to that :-))
