[antlr-interest] "protected" lexer rules

[Terence Parr]

Ok, folks, time to come up with a better name for lexer rules that are 
not real tokens (they are only rules called by other rules).  Currently 
it's "protected", which is hideous:

FLOAT : (DIGIT)+ '.' DIGIT | (DIGIT)+ ;

protected
DIGIT : '0'..'9' ;

Ick.  So, should it be an option or keyword?  What would the name be?  
I can't even describe it exactly even in two words. :(

"non token"?  "method"?  "macro"?  "internal"?

Help!

I need to implement this now in the 3.0 system.
