<div class="Ih2E3d">> This is similar to implementing "Undo" functionality in applications.<<br>
<br>
</div>In a quite-high-level language (like Python, but not necessarily in<br>
Python itself) it may become eventually advantageous to add some (even<br>
limited) built-in form of undo. Both to give a simpler way to<br>
implement a undo functionality into user-level programs (that is to<br>
implement the Undo command in a program with GUI), but more<br>
importantly to help the programmer too in some more general<br>
programming tasks.<br>
<br>
So it's probably a feature we'll see in the next generation of high-<br>
level languages, among few other features that today are missing in<br>
Python (only sometimes missing for performance reasons).<br>
