I'm not sure what your point is. I rely quite a bit on randomly generated tests, and of course, any multithreaded app has nondeterministic elements that can be hard to replicate. For that matter, if you are simply experimenting with new code at the REPL, it might not always be clear what sequence

doall doesn't recurse, so you are not realizing the lazy-seq, you want something like [msg (doall sig-strs)] if you are looking to play around with io stuff, I recommend looking in to using reducers for io, they allow you to sort of invert control, keeping the nice property of with-open always cle

For Vim users, I ported the debug repl. This is a tool that allows you to create a REPL in the middle of the call stack, which allows you to suspend the evaluation of functions, lazy seqs, etc, and then inspect the locals and globals at that location. If you've already installed Fireplace, then
