* Examples in C++
You can run `make` to compile these examples. And `make clean` to tidy
afterwards.
** simple.yy - Simple example in C++14
A very simple example in C++, based on variants and symbol constructors.
Variants allow to use any C++ type as semantic value type, and symbol
constructors ensure consistency between declared token type and effective
semantic value.
Run as `./simple`.
Extracted from the documentation: "A Simple C++ Example".
https://www.gnu.org/software/bison/manual/html_node/A-Simple-C_002b_002b-Example.html
** variant.yy - Self-contained example in C++98
A varition of simple.yy, in C++98.
Run as `./variant`.
** variant-11.yy - Self-contained example in modern C++
Another variation of simple.yy, closely related to the previous one, but
exhibiting support for C++11's move semantics.
Run as `./variant` or `./variant NUMBER`.
