Cleanly Cloned Version 2.4.0 is not working correctly.

[Sebastian-Lamay]

What version of OpenSCAD are you on?
OpenSCAD version 2021.01
Cloned the Master Branch so 2.4.0

Describe the bug
When running any of the examples in keys.scad there are Warnings on the console, Keys don't generate correctly.

Error Log shows:
WARNING: Can't call function on dynamically scoped variable in file functions.scad, line 29
WARNING: undefined operation (number + undefined) in file functions.scad, line 29
WARNING: undefined operation (undefined * number) in file key.scad, line 53
WARNING: Unable to convert cube(size=[18.24, undef, 0.01], ...) parameter to a number or a vec3 of numbers in file src/key.scad, line 53

To Reproduce
Steps to reproduce the behavior:

1. Clone Master Branch
2. Open Keys.scad
3. See error

Additional context
Version 2.3.0 seems to work fine on my machine. I'm running on PopOs

I am also hitting this.
The issue seems to be in file functions.scad at line 30

function key_height_at_progress(progress = 0) = $bottom_key_height + ($unit * ($key_height - 1)) - $height_difference + $side_sculpting(progress);

The function $side_sculpting(progress) is not implemented in this file as mentioned in the TODO above.

If I remove it the default key cap is generated fine.

function key_height_at_progress(progress = 0) = $bottom_key_height + ($unit * ($key_height - 1)) - $height_difference;

But I cant generate different keys after fixing the warnings still...

I fixed this by running KeyV2 through the latest AppImage developer snapshot of OpenSCAD (2023.09.30.ai16393 (git f41aefc37)).

Hope this helps.
