+* let the various list types be hashtables where appropriate
+* check out jit-dynamic
+* fix arginfo with nullable types
+* pemalloc
+* think about a better system for EXTVARs, separate \set and \get functions are clunky
+* impl_def_val: allow num_exp
+* fix right recursion of let_exp and set_exp
+* numeral suffixes
+* improve arargs support, currently it's impossible to map e.g. curl_easy_setopt
