@ -45,9 +45,12 @@ Currently missing big features (TODOs) are:
- ~~Built-in Int/Float division and modulo~~ (DONE)
- ~~Loops~~ (DONE)
- ~~Intrinsic functions~~ (DONE)
- ~~Ability to specify types in literals~~ (DONE)
- Debug Information (PARTIALLY DONE)
- Ability to specify types in literals and variable definitions
- Not-Unary
- Importing types from other modules
- Importable binops?
- Ability to specify types in variable definitions
Big features that I want later but are not necessary:
- Associated functions
