<div dir="ltr">Okay, I've made a first attempt at this (just now pushed to git). I added the ability to add new mixins (via the drracket:get/extend:extend-* functions) at any time (as long as you call a function to explicitly enable that feature). DrRacket makes no attempt to adjust any existing objects that have been created but, for the most part, as long as you create a new frame after doing your new extensions, things should work, I think.<div> <br></div><div style>Also, if you set the PLTDRRPEL environment variable then you'll get a REPL.
