Yep, or does it drops off the lambda and formals from the list, thus
losing the source position info (that being on the start of the list
only)?

        (read-enable 'positions)
        (define (x) (display 'hello))
        (source-properties (procedure-source x))
        => ()

Another use for positions on procedures I mentioned another time was
to show that info in a backtrace.  When you just see "<procedure #f>"
it's a bit of a guessing game to tell where the offending bit actually
came from.

All this would be for under --debug only, it wouldn't need to bloat
normal operation.
