[racket] How to view source code of procedures? MIT scheme "pp" equivalent?

I use Geiser mode but find it pretty lacking for this purpose.  Some of the

anything.  It may be that I have to upgrade my version or look into the
configuration options.

2. The general way to go about this would be to use
