5c38f7dfd7 Don't allow fn@ items
fn@ is intended to be caputring but isn't implemented.

9efdd0f326 Merge ast::proto_shared and ast::proto_closure
Now they are both just proto_shared and proto_shared takes an
argument indicating that it is sugared as 'lambda'

f324704c0a Parse obj methods as proto_bare
I don't know if this is the right thing to do, but it works
and it lets 'fn' always mean proto_bare

070c39ca1d Split parsing of fn proto between types, items and anons
The meaning of various fn incantations is going to get temporarily confusing

cbe8da0655 make treatment of unchecked/unsafe blocks more uniform
also repair various errors in the parser related to such blocks.
rename checked_blk to default_blk to reflect the fact that it
inherits its purity from the surrounding context.

9c46cc58cb Add a temporary syntax for bare functions
Bare functions will be represented as 'fn#' until they're implemented. Then
we'll switch it over to just 'fn'.

f26e770745 Make 1-1 parse again
Issue #954

This is not a very elegant fix -- we should probably do something with
constant folding to handle negative-int alt patterns in the future.

133d36f452 Require body of else-less if expressions to be a value-less block
For consistency with other constructs that could not possibly return a
value (say, loops).

d7587c1eda Change convention for specifying referenced argument
It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to
be used to refer to self and maybe to closure.)

Also allows non-referenced args to be implicitly copied again.

0b34e0e60b Introduce new semicolon rules
- Loop bodies and resource constructors aren't allowed to have
  trailing expressions anymore.

- An expression that ends* in a block without trailing expression can
  can not be called, indexed, or subscripted.

- Only expression-statements that end* in a block without trailing
  expression can omit their semicolon.

*) 'Ending in a trailing expression' is defined as being a block or
   construct-ending-in-a-block (if, alt) that either ends in an
   expression itself, or ends in another block-like expression that
   has a trailing expression (by these same rules).

be5537e95f Be more strict about what constitutes a block expression
Blocks (or statements involving blocks) that end in a semicolon are no
longer considered the block-expression of their outer block. This used
to be an expression block, but now is a statement block:

    { if foo { ret 1; } else { ret 10; } }

This helps clear up some ambiguities in our grammar.
