df49fb3dc3 - Preliminary draft of what might become a real spec 
- All text taken from go_lang.txt (which is unchanged),
but added a contents section, and sorted the contents
section in a hopefully sensible manner to give it more
structure
- Reordered text to match order of contents section,
did not adjust the language (needs to be done),
but removed sections that were dulicates or invalid

High-level organization of the doc:
- Introduction
- Notation
- Source code representation
- Vocabulary
- Declarations and scope rules
- Types
- Expressions
- Statements
- Function declarations
- Packages
- Program initialization and execution

I hope this new structure will make it much clearer which
pieces are missing and where they need to go. go_lang.txt
has grown somewhat unstructured and new text was added as
we saw fit.

de5442893d A small but powerful change in constant declarations. Proposal by ken 
after some discussion about enums. Implementation should be trivial.
Wording in the doc should be improved, probably.

d222c65477 Introduced forward declaration of types per discussion with ken. 
A forward-declared (or not yet fully defined) type must be used
to construct (mutually) recursive type declarations. This simplifies
the compiler and resolves the issue at which scope the forward-
declared type is to be declared.
