133c68e9ac Simplification of Conversions section: 
- leave only basic type conversions in that section
- we have a section of composite literals which covers those
- we have a section prepared (but not written) on type guards
- the built-in function "convert" doesn't need to be exposed
  as it is redundant

separate between ints and floats, added language regarding the
type of numeric literals)
- added language with respect to the scope of labels
- introduced ideal types for the purpose of the spec
- added language to expressions, operands
- added some more formal language about ideal type conversion
  (probably not 100% correct yet)

7231ceb714 Proposal for new function type syntax as suggested by ken: 
- removed "func" from function type
- make it work by changing composite literal syntax to use {} instead of ()

FunctionType is now more in line with the rest of the declarations, as the
keyword "func" is now really part of the declaration and not part of the type.

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.

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.

0d1e90be17 - added 'nil' keyword to lang doc 
(did not add 'true' and 'false' because I think these don't need to be
  keywords, they can be recreated from whole cloth)
- added 'new' syntax to expressions
  (this is needed because of the type as 1st argument - the expression
  list is probably not yet implemented, but I think we may want it
  eventually)
- removed optional ';'s in sieve example - make it more concise
- fixed several bugs in go.atg, no parses sieve
- added sieve as test case
