A terminal session begins by listing the contents of the current directory, which contains three files; "hello", "world" and "hello world". The filename variable is set to "hello world" and then rm $filename is executed, without quoting the variable. The directory contents are listed again, showing "hello" and "world" left behind.

Can your shell do this?
A terminal session demonstrating features of the xc shell. A list of three items, "echo", "hello", and "world", is assigned to a variable, and then various ways of utilizing this list are demonstrated. $x prints "hello world". Two printf commands are used to show that $x expands into three arguments, but $"x expands into just one. The use of $x(1) and $x(2-) demonstrate access to individual list items and a subset of items respectively.

I've also heard promising things about this platform continuing to move towards a more practical open and decentralized model, but feel free to disillusion me on that point.
