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.

5d6eba80f8 generate an error if the foreward 
declaration of a func does not exactly
match the actual (or another foreward)
declaration. the reason is that when
there are 2 declarations of a function,
the names of the parameters are taken
from the first. thus
   func x(a int);
followed by
   func x(b int) { ... }
will have the parameter named "a" and
"b" will be undefined.

d2490e7419 - Implemented simple rule for optional semicolons: 
Semicolons are terminators for statements as in C,
  but if followed by a "}" they are not required.
  This is easy to understand and produces the desired
  result for statements.
- Updated todo.txt.

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
