You go into your homemade library of code to re-use some piece that you

the code this time you find an undiscovered bug or some part of the
code that looks like you where on drugs when you made it.

This is why it's good to write this kind of thing as functions. Then if you find some great problem with it later, you can drop in the replacement functions and the code that calls it (hopefully) won't need modification.

Of course, it's easier to be cleverer after the event.
