It looks like that. Except `iter` should be defined in the namespace of the
REPL.
Maybe iter is complicated, but at least sum and vals.
Hmm. The procedure “foo” without the "(trap-here)” is just a simple program
(using named let) that I want to debug.
So I add the “(trap-here)” to get into the debugger at that spot in the
program, like I would add “pdb.set_trace()” in python.

How do you access variables in the REPL?
