Try Rust

Based onIntroduction - Writing Interpreters in Rust: a Guide we explore if it's fun to rewrite Mosh in Rust.

Goals

• We'll see if it's practically possible to rewrite Mosh in Rust with current design (Compiler written in Scheme).
• We'll see all basic building blocks work.
  • Scheme object with tag bits.
  • GC
  • Run small list of instructions in VM
  • UTF-8
  • File I/O

Non Goals

• Fully rewrite Mosh.
• Well designed Rust code.

Milestones

• M1: Just build the example
• M2: Define Fixnum and it's predicate
• M3: Create simple VM to just evaluate constant
• M4: Update VM to run addtion
• M5: Come up with a rough idea of how we implement GC.
