Agreed.  There are more functions on this list, including
location_default, and, after all why not, yylex (I mean the
invocation).  BTW we don't need to make them all function, the
interface makes it easy for us to inline them if needed.

I agree naming is nice, but let's keep our set of lexical construct
simple.

    lhs:
        rhs1 rhs2      %rule L1 { $$ = new_lhs ($1, $2); }
      | rhs1 rhs2 rhs3 %rule L2 { $$ = new_lhs ($1, $2, $3); }
