Once I have loaded a file using require, is there a clean way to reload the file?

Reloading the file is easy. It's unloading the effects of the previous version that relies on a lot of assumptions and limitations.

But your question is wrong. The problem is your use of require to load something other than a module. You want do.

That said, needing do is a sure sign of a bad design. This is no exception.
