Robert Griesemer 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

Robert Griesemer ad71110669 - rewrote section on numeric literals (grammar easier to read,
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)

Robert Griesemer 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.

Robert Griesemer 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.
