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.

David Majda	409ddf2ae8	Formatted all grammars more consistently and transparently This is purely cosmetical change, no functionality was affected (hopefully).	14 years ago
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"?)	14 years ago
