This is great to see; instaparse is crucial for some of my projects and I appreciate the ongoing development.
I've noticed two issues with 1.4.4 which I want to run by you: 1. insta/parser has a breaking change, in that it no longer accepts resources directly I can work around this easily by slurping before hand, but this may've been an accidental breakage. 2. insta/defparser doesn't support the same optional parameters as insta/parser Specifically, I've found that it doesn't like when I specify :auto-whitespace, which is a feature on which I rely heavily for my grammar. Finally, given the possible performance benefits, do you recommend everyone (Clojure and ClojureScript) prefer defparser, where possible? Thanks!
