 ## What's missing ?
 
 - [x] Constant evaluation and constant folding - Folding and precomputing every expression that can be calculated at compile time. Which allows to check if a given constant expression is actually something that can be computed at compile time
-  - [ ] Constant expressions with concrete types without casting
 
 - [x] Untyped types - Context dependent type assignment of constant expressions, this is a feature I really loved in Go, it makes constants work very well with a very strict type system and it makes errors like overflow of constants in C due to bad size specifier impossible
   - [x] Infinite precision integers in constants

 - [x] You can't alias Lambdas because they are not evaluated as constant.
   I used a little simplification where lambdas and structs were marked as such
   in parsing I think. BUT Structs work so it's maybe just a little fix of constant
