Suppose someone asks you what the "foo" variable is for, what are you
going answer?
The point is: let the variable name reflect what it contains, don't
re-use the same variable for something else. That way your code will be
a lot more readable.
let fooline = "one,two,three"
let foowords = split(fooline, ',')

For large projects, Team Leaders use sophisticated project management software
to keep track of who's doing what. The software collects the lies and guesses
of the project team and organizes them in to instantly outdated charts that
are too boring to look at closely. This is called "planning".
