Describing my debug workflow woes at clojure/west, it was suggested to me
that I could jump into the jar file for a library and add print statements
to elucidate its inner workings. I guess this is supported in emacs? Jump
into the library source jar, edit, reload into the repl? How does this
Don't worry about the jar, especially. You can have your own git checkout
of the upstream project you're working with, and that'll work just fine.
Open a source file you need to work with, connect with nrepl, edit a
function, and eval -- that should be enough.

Checking out a project your project depend on, finding the right
version, etc. is quite cumbersome.
With Emacs/nrepl, you can just press M-. over any function to jump to
the definition, even when it's inside a jar.
You can also edit and reload it (via C-c C-c). I don't think you can
save it, but
This seems like the right approach, but something is odd about the
namespacing. Details:
0) using vim-fireplace
1) I jump into honeysql-0.4.2.jar::honeysql/format.clj
2) edit the format fn to always return foo, and eval the new fn definition
3) Eval (format {:select [5]}) in the format.clj
