*** A C++ native GLR parser
A new version of the generated C++ GLR parser was added as "glr2.cc". It
is forked from the existing glr.c/cc parser, with the objective of making
it a more modern, truly C++ parser (instead of a C++ wrapper around a C
parser). Down the line, the goal is to support `%define api.value.type
variant` and maybe share code with lalr1.cc.
A new version of the C++ GLR parser was added: "glr2.cc". It generates
"true C++11", instead of a C++ wrapper around a C parser as does the
existing "glr.cc" parser. As a first significant consequence, it supports
`%define api.value.type variant`, contrary to glr.cc.
The current parser should be identical in terms of interface, functionality
and performance to "glr.cc". To try it out, simply use
It should be upward compatible in terms of interface, feature and
performance to "glr.cc". To try it out, simply use
