Ranges

The term [-1, 0, 1] can be replaced with a range expression [-1..1], which yields the array we need:

use std::geo2d::*;
use std::ops::*;

(Circle(d = 6.51mm) - Circle(d = 4.8mm)).translate(x = [-1..1] * 8mm);

A range expression has the syntax [m..n] where m and n have to be of type Integer.

As you might have mentioned µcad ranges differ from ranges in other languages (like Rust): They include the end value - in Rust you would have to write [-1..=1] to achieve the same if you write [-1..1] in µcad.
