David Majda 5f810f803b Make example grammars compatible with Rhino 15 years ago
David Majda ee8c121676 Use labeled expressions and variables instead of $1, $2, etc.
Labeled expressions lead to more maintainable code and also will allow
certain optimizations (we can ignore results of expressions not passed
to the actions).

This does not speed up the benchmark suite execution statistically
significantly on V8.

Detailed results (benchmark suite totals):

David Majda 409ddf2ae8 Formatted all grammars more consistently and transparently
This is purely cosmetical change, no functionality was affected
(hopefully).

David Majda 698564a3c2 Replace ":" after a rule name with "="
I'll introduce labelled expressions shortly and I want to use ":" as a
label-expression separator. This change avoids conflict between the two
meanings of ":". (What would e.g. "foo: 'bar'" mean?  Rule "foo"
matching string "bar", or string "bar" labelled "foo"?)
