experimental.group() function

The experimental.group() function introduces an extend mode to the existing group() function.

Function type: Transformation

The experimental.group() function is subject to change at any time. By using this function, you accept the risks of experimental functions.

This specific function will be removed once the proposed extend mode is sufficiently vetted.
