-* Language independent actions

-Currently bison, the generator, transforms $1, $$ and so forth into
-direct C code, manipulating the stacks.  This is problematic, because
-(i) it means that if we want more languages, we need to update the
-generator, and (ii), it forces names everywhere (e.g., the C++
-skeleton would be happy to use other naming schemes, and actually,
-even other accessing schemes).
-
-Therefore we want
-
-1. the generator to replace $1, etc. by M4 macro invocations
-   (b4_dollar(1), b4_at(3), b4_dollar_dollar) etc.
-
-2. the skeletons to define these macros.
-
-But currently the actions are double-quoted, to protect them from M4
-evaluation.  So we need to:
-
-3. stop quoting them
-
-4. change the [ and ] in the actions into @<:@ and @:>@
-
-5. extend the postprocessor to maps these back onto [ and ].
