The thing is, if I am doing code review or telling someone they are not following Single Responsibility Principle by throwing everything in main, I will tell them to:
bar0 = process0()
barN = processN()
baz = doing_stuff(bar0, ..., barN)
Foo bar baz is a specific way to show theory, principles, and has it's place. Much like the comment below . and x in math.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
