To Do

[ ] Consider returning data type errors rather than evaluating errors to nil [ ] Add tests to make sure McCarthy scope contains what we expect it to [ ] Pass env to macro [ ] Add line and column to errors where applicable [ ] Passing lambdas to other lambdas is a lil weird... figure it out [ ] McCarthy things need to be implemented [] Car [] Cons [] Cdr [] Equal [] quote [ ] Maybe more [] McCarthy context??? as a type of Rust context? [ ] Make sure all McCarthy things are added [ ] Lib user defined Rust Contexts [ ] Rust context of lib that I find useful [ ] Like print [ ] Add/Subtract [ ] Stuff that isn't pure McCarthy [ ] Figure out the difference and standard practices between e2e tests and lib unit tests [ ] Syntax parsing is a wreck, refactor to make it easier to read [ ] Semantic parsing is probably redundant and the work being done there is probably better off being done in syntax parsing [ ] Garbage collector [ ] Evaluate List should be refactored into more functions so its easier to read [ ] Allow multiple lists in root, without tacking on a root list as a new function. Maybe as a vector of refvals [ ] Maybe strings should be lists of chars? Or maybe permanently quoted symbols? Pick one [ ] List macro [ ] Label macro [ ] let macro [ ] arbitrary cdaddr function [ ] Maybe mccarthy functions should be "specials", separate from macros? decide. [ ] From SX for SXRef [ ] From inner for SXRef [ ] From inner for SX [ ] Better toString for Function [ ] Better toString for Macro [ ] Find a way to implement PartialEq on RustFunction [ ] Find a way to implement PartialEq on RustMacro [*] Move closures in McCarthyScope to their own functions?
