60ce95d7a1 code changes for array conversion. 
as a reminder, the old conversion
was that you could write

	var arr [10]byte;
	var slice []byte;
	slice = arr;

but now you have to write

	slice = &arr;

the change eliminates an implicit &, so that
the only implicit &s left are in the . operator
and in string(arr).

also, removed utf8.EncodeRuneToString
in favor of string(rune).

c5c577c1ff - minor tweak to composite literal production: 
renamed PairExpr -> KeyValueExpr and PairExprList -> KeyValueList
(to match corresponding nodes in AST per rsc' suggestion)

5958dd6f94 Suggested tweaks up to package section. 
Major ones:
* Be consistent: "numeric type" and "arithmetic operator".
* if/swtch take "simple statement" not "short variable declaration".
* There was a comment that implied for x,y := range z() might
  evaluate z() multiple times.  I deleted it.

5af7de3fe3 Updated the section on Types. 
Moved assignment compatibility to its own small section. Although most rules are type-specific,
some are not and it reduces redundancy to combine them.
Also, more experimentally, wrote a section on comparison compatibility.
