I think moving the transcript port from the property list to the port
itself would be worthwhile because this call chain happens a lot. It
would make ports a little bit bigger, but I don't think that's
Arggh Good catch. Let's move the transcript operations as you suggest.

I did integrate-operator because the argument `object' is duplicated.
The slightly better job is offset by the potential for bugs later on.
I didn't realize until you said this that DEFINE -
It's worth the trouble in some situations. Generally I only use it
when the parameters are referred to exactly once, or when I know that
the arguments are always simple expressions without side effects.
There is code in the compiler to optimize expressions of the form

Something to keep in mind is that define-integrable normally has no
effect outside of the file that it appears in. It's rare for someone
to use the integrate-external declaration.

That's pretty hard to prove unless all the calls between the
argument binding and the argument use are primitives or known to be
effect-free. For the most part, you can get away with it because
