// Two workarounds exist, neither of which are needed in newer versions of OpenSCAD. The workarounds solve the problem because
// **modules** execute after their parent, so the `$` variables **are** available in modules. You can put your assignments
// in a `let()` module, or you can wrap your child in a `union()`. Both methods appear below.
// ```
// xcopies(n=10, spacing=10)
// text(str($idx));
// ```
// Figure(2D): This example shows how we can use `$idx` to produce **different** geometry at each index.

// Figure(2D): Here the children are sometimes squares and sometimes circles as determined by the conditional `if` module. This use of `if` is OK because no variables are assigned.

// Figure(2D): Suppose we would like to color odd and even index copies differently. In this example we compute the color for a given child from `$idx` using the ternary operator. The `let()` module is a module that sets variables and makes them available to its children. Note that multiple assignments in `let()` are separated by commas, not semicolons.

If you want to avoid repeating your code for each case, this requires storing a transformation matrix in a variable and then applying it using `multmatrix()`. We wrap our code in `union()` to ensure that it works in OpenSCAD 2021.01.
