+ Support parametric types.
+ There are two issues to handle: first scanning nested angle bracket pairs
+ to support types such as std::pair< std::string, std::list<std::string> > >.
+
+ Another issue is to address idiosyncracies of C++: do not glue two closing
+ angle brackets together (otherwise it's operator>>), and avoid sticking
+ blindly a TYPE to the opening <, as it can result in '<:' which is a
+ digraph for '['.

+ Finer input type for yytranslate.
+ This patch is debatable: the tradition expects yylex to return an int
+ which happens to correspond to token_number (which is an enum). This
+ allows for instance to return characters (such as '*' etc.). But this
+ goes against the stronger typing I am trying to have with the new
+ lex interface which return a symbol_type. So in this case, feed
+ yytranslate_ with a token_type.

Use b4_type_names for the union type.

type of all the symbols, with a lot of redundancy. Now iterate over the
