Field access now works, somehow! It was easier then I thought,

probably introduced a bunch of bugs though

# The Core Language # The Core Language
A compiled language that assumes C as base reality but it also has lots of ideas taken from Jai, Go like type system, order indepent declarations using Ion algorithm. Syntax currently is whitespace significant. Made to practice language development, **it's not supposed to be used**. It has lot's of ideas from modern programming languages that you would not find in any compiler book. It supports **modules** combined with **ordered independent declarations** and **lazy typechecking**. Also **runtime reflection**, **slices** and other standard features you would find in C.

The language is currently **very debuggable**. It can produce readable C code with line directives. This allows you to debug the programs with Visual Studio with full source mapping, exactly like you would debug C programs. The language is currently **very debuggable**.
