+ 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.

+
+ Fuse the three stacks into a single one.
+ In order to make it easy to perform benchmarks to ensure that there are no
+ performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
+ lalr1-fusion.cc will replace lalr1.cc.
+
+ Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
+ test suite, the user must install a symbolic link from lalr1.cc to it.
+
+ Instead of having three stacks (state, value, location), use a stack
+ of triples. This considerably simplifies the code (and it will be
+ easier not to require locations as currently does the C++ parser),
+ and also gives a 10% speedup according to etc/bench (probably mainly since
+ memory allocation is done once instead of three times).
+
+ Another motivation is to make it easier to destruct properly
+ semantic values: now that they are bound to their state (hence
+ symbol type) it will be easier to call the appropriate destructor.
+
+ These changes should probably benefit the C parser too.
+
+ * data/lalr1.cc: Copy as... * data/lalr1-fusion.cc: this new

+ * data/lalr1.cc (parser::yypush_): New.
+ (parser::yynewstate): Change the semantics: instead of arriving to

+
+ Use variants to support objects as semantic values.
+ This patch was inspired by work by Michiel De Wilde. But he used Boost
+ variants which (i) requires Boost on the user side, (ii) is slow, and
+ (iii) has useless overhead (the parser knows the type of the semantic value
+ there is no reason to duplicate this information as Boost.Variants do).
+
