“Fun” C++ library that interprets ASCII figures in code - what is it called? (“Multi-Dimensional Analog Literals”)

问题

A while ago I stumbled upon a C++ gem, a set of classes that through operator overloading and possibly some preprocessor tricks, let you define variables using in-code ASCII art:

Line x = |-----|;    //x is 5
Line y = |---|;      //y is 3

Rectangle r = +---+
              |   |
              +---+; //r is 3 by 1

and IIRC, it even had support for 3D figures!

But for the life of me I cannot remember the name of this library/header file/set of classes. What is it called?

I believe you are after Multi-Dimensional Analog Literals
