Towards Zilch v1

[Mesabloo]

Zilch features are under heavy discussion for the first 3 versions in #4.
However, features must be planned at some point for the first version (this would be too unrealistic to fit all those at once).

For Zilch v1, these features will be considered:

• Basic low-level types such as u32, ptr(s8), char, etc. No reference type considered for now.
  Issue: Basic data types and values for Zilch #16
• Structures and enumerations with pattern matching.
  Issue:
• Higher order functions with lambda expressions (compiled to closures).
  Issue: Anonymous functions #17
• A very simple C FFI.
  Issue: FFI targetting C #19
• Algebraic effects.
  Issue: Add algebraic effects to Zilch #7
• A very simple module system as originally imagined.
  Issue: Modules #18

The current execution model is not yet specified.

Principal issues will be put here to track progress of the implementation.
All of this will be formalized before (not necessarily completely, but at least 80%) in the specification.
