Further thoughts/still to do: Further thoughts/still to do:
* Functions
* anonymous, simple
* named, simple
* anonymous, complex?
* named, complex
* with docstrings?
* Cond expressions
* Loops
* Structs
* Namespaces
* Types (:|)
* Modules
* Add `as` clauses to patterns
* Add `when` clauses to patterns
* var/mut
* ref/swap
* Splats in lists, hashmaps, sets
* AST nodes should include tokens/locations * AST nodes should include tokens/locations
- at current, only atoms do this - at current, only atoms do this
* Improve error handling in hashmap parsing * Improve error handling in hashmap parsing
* * Consider error handling in match expressions
* Add treatment of ignored variables
Other quick thoughts: * Placeholders
* How much in parser, how much in analysis?
* Placeholders
* Does this want to happen in parsing or in analysis?
For future correctness checks:
