+
+ Add "%define assert" to variants.
+ This is used to help the user catch cases where some value gets
+ ovewritten by a new one. This should not happen, as this will
+ probably leak.
+
+ 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.
+
+ * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
+ (b4_variant_if): New.
+ (variant::built): New.
+ Use it whereever the status of the variant changes.
+ * etc/bench.pl.in: Check the penalty of %define assert.

+ * etc/bench.pl.in: No longer use the pseudo directive %variants,
+ just use %define variants.

+
+ Make variant.yy more complex.
+ std::list cannot be copied via memcpy, they are more demanding than
+ std::string. Use one std::list to strengthen the test.
+
+ * examples/variant.yy: Use lalr1-fusion.cc, not lalr1.cc.
+ Adjust.
+ Create a list of strings, instead of a single large string.
