Then whatever you changed, you should change back to the way it was.

That's the most important lesson here: never make two or more unrelated
changes to a program unless you have a backup of the working file.

An excellent way to manage this process is by using a revision control
system like Mercurial (hg) or equivalent. But at the very least, whenever
you change a working program, you should confirm it is still working before
making the next change.

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure
enough, things got worse.
