[antlr-interest] speaking of => etc...

[Terence Parr]

So, we have a syntax / notation problem for predicates now.  I am  
proposing the following new notation:

[...]		optional subrule
(...)?		syntactic predicate
a : (alt)? | ... ;	syntactic predicate wrapping whole production
{...}?		_hoisting_ disambiguating semantic predicate
{...}=>	gated semantic predicate
rule		rule reference
<rule(args)>	rule reference with args
ID		token reference
<ID(args)>	token reference with options

The blog shows my reasoning:
