• Move into a utility sub package:
  • dmd.console
  • dmd.entity
  • dmd.utf
  • dmd.root.array
  • dmd.root.hash
  • dmd.root.outbuffer
  • dmd.root.stringtable
• dmd.errors
• Make wrappers switch to D's variadic arguments

The language is composed of types, literals and statements. Types are a definition of what a literal can be.

Literals are:

- Number
- String
- Function body with prototype
- Reference to variable
- Initialized template
- Comment
