 ## 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
-
-- [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 using big ints! No more overflows or underflows (at least at compile time).
+- [x] Typechecking - very strict typesystem, inspired by Go, no implicit conversions outside of special types like void or Any.

 - [x] Module system
   - [x] Lazy evaluation of modules (unused code is not compiled or typechecked)
   - [x] Import module, load project file distinction
+  - [x] Linking to libraries through importing a module, module calls ```#link``` and that is added to linked libraries.
 
 - [x] Order independent declarations - The ordering of functions in code files or modules does not matter, compiler figures all that stuff out for you. "main" can be wherever you want it to be and all functions should be available without problems
