Go to bar X, order a Y, and Z it [eg 'compress', 'gzip', 'drink']
How do you show that x/y/z are

Better design is to make the argument list a parameter to the ‘main’

Long ago, I saw a C program that took another C program as input. It would
output a copy of the original C program, interspersed with fprintf's that
would display the text of the line current being executed.
You might write something similar for Python, perhaps outputting the line
being executed

I have some code which produces a list from an iterable using at least
one temporary list, using a Decorate-Sort-Undecorate idiom. The algorithm
