+
+ 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.

+ make_symbol provides a means to construct a full symbol (kind, value,

+
+ Change the handling of the symbols in the skeletons.
+ Before we were using tables which lines were the symbols and which
+ columns were things like number, tag, type-name etc. It is was
+ difficult to extend: each time a column was added, all the numbers had
+ to be updated (you asked for colon $2, not for "tag"). Also, it was
+ hard to filter these tables when only a subset of the symbols (say the
+ tokens, or the nterms, or the tokens that have and external number
+ *and* a type-name) was of interest.
+
+ Now instead of monolithic tables, we define one macro per cell. For
+ instance "b4_symbol(0, tag)" is a macro name which contents is
+ self-decriptive. The macro "b4_symbol" provides easier access to
+ these cells.

+
+ Add "%define assert" to variants.
+ This is used to help the user catch cases where some value gets

+
+ Unfortunately this uncovered a bug in the C++ parser itself: the
+ lookahead value was not destroyed between two calls to yylex. For
+ instance if the previous lookahead was a std::string, and then an int,
+ then the value of the std::string was correctly taken (i.e., the
+ lookahead was now an empty string), but std::string structure itself
+ was not reclaimed.
+
+ This is now done in variant::build(other&) (which is used to take the
+ value of the lookahead): other is not only stolen from its value, it
+ is also destroyed. This incurs a new performance penalty of a few
+ percent, and union becomes faster again.
