My question is:

It would be really nice to print the source code of a known procedure on
the repl, in order to get a quick view of what it does. Or, the "pa"
function which prints out the arguments of a procedure is even more useful.

Thanks a lot for the responses. I really appreciate it.
It's reassuring to hear many of my assumptions echoed back. And the
mention of the Expression Problem has led me to uncover additional articles
on the topic besides the original Krishnamurti, et al paper.
Scott.
Rack
better suited to
an object oriented design vs functional and vice-versa, or is the power of
such languages as racket reducing the OO vs Functional debate to a
religious war, whereby both methods achieve reuse and it's just a matter of
preference?
Thanks a lot.

The reasons are obvious. I'm just wondering if there's a more robust way
of dealing with these types of scenarios that I'm missing? I thought of
combining an (~or (~and clause but that becomes very tedious, and leaves
the duplicate problem uns
