description::
Operating on functions instead of numbers, what results is not a result of the calculation, but a structure that represents that calculation.

examples::
code::
// example
a = 0.8.linexp(0, 1, 40, 20000); // map (0..1) to exponentially to human frequency hearing range
a = { b }.linexp(0, 1, 40, 20000); // result is  a NAryOpFunction
b = 0.1;
a.value; // now it is evaluated, and the result is calculated
b = 0.5;
a.value; // again, with a different value.
::

code::
// sound example
(
var a = { 1.0.rand };
var b = a.linexp(0, 1, 40, 20000);
fork {
	15.do {
		(instrument: \default, freq: b.value).play;
		0.3.wait;
	}
}
