 ### Reading notes
 
+See [Open Issues](https://github.com/ldemailly/gorepl/issues) for what's left to do

 - See the commit history for improvements/changes (e.g redundant state in lexer etc)
 
 - [x] interface nil check in parser
 
 - [x] Do we really need all these `let `, wouldn't `x = a + 3` be enough? made optional
-   - [ ] remove let entirely ?
-   - [ ] no let for macros?
 
-- [ ] Seems like ast and object are redundant to a large extent

+- [x] use + for concat of arrays and merging of maps
 
 - [x] call maps maps and not hash (or maybe assoc array but that's long)
 
 - [x] don't make a slice to join with , when there is already a strings builder. replace byte buffers by string builder.
 
 - [x] generalized tokenized built in (token id based instead of string)
 
-- [ ] Add "extension" internal functions (calling into a go function), with variadic params, param types etc
+-  Add "extension" internal functions (calling into a go function), with variadic params, param types etc
 
 - [x] Identifiers are letter followed by alphanum*
 
 - [x] map of interface correctly equals the actual underlying types, no need for custom hashing
   -> implies death to pointers (need non pointer receiver and use plain objects and not references)
 
-- [ ] unicode
+- unicode (work as is in strings already)
 
 - [x] flags for showing parse or not (default not pass `-parse` to see parsing)
 
 - [x] file input vs stdin repl (made up .gr for gorepl)
 
-- [ ] actual name for the language - it's not monkey (though it's monkey compatible, just better/simpler/...)

 - [x] switched to non pointer receivers in Object and (base/integer) Ast so equality checks in maps work without special hashing (big win)
