FastIO will not accept defined constants

[LaZsolt]

Yes, FastIO can not accept defined constants or variables. It is not an error. FastIO not designed for such a type of source.

// Fast.IO demostration
// =======================================================
// Important note:
// fast_io interface is implemented by macro definition
// Compare to arduino's digital i/o interface, fast_io
// is small and fast.
// But fast_io has some limitations:
// 1. only support digital mode i/o operation;
// 2. fastio DO NOT support avriable as arguments!
// e.g, you can not use fastio as following:
// int led = 10;
// fastioMode(led, OUTPUT);
// but you can use it like this:
// #define led 10
// fastioMode(led, OUTPUT);
// or fastioMode(10, OUTPUT);
// or fastioMode(D10, OUTPUT);
// ========================================================

Then you should change the comment:

// but you can use it like this:
// #define led 10
// fastioMode(led, OUTPUT);
// or fastioMode(10, OUTPUT);
// or fastioMode(D10, OUTPUT);

Because this code will not work.
