+[ ] Check interpret-fn-inner ctx for cycles/bugs
+
+Re-add processes to the language
+[ ] Write send as function

 [ ] Merge new interpreter
 
+Write a compiler: desugaring
+[ ] `...` to `..._` in tuple & list patterns
+[ ] placeholder partial application to anonymous lambda
+[ ] word -> :[word] word in pairs (patterns & expressions)
+
+Write a compiler: correctness
+[ ] check for unbound names
+[ ] check for re-binding names
+[ ] check that recur is in tail position
+[ ] check that recur is only called inside loop or fn forms
+[ ] check ns accesses
+
+Write a compiler: optimization
+[ ] devise tail call optimization
+
+Next steps
 [ ] Get drawing working?
