Isolating global changes between modules in node.js

It seems like if I modify, say, Object.prototype, that seems to be visible across all modules. It would be very nice if these global changes could be isolated so that a module is protected from being affected by modules is doesn't require.

Is this in any way possible?

Object.prototype is an object, and there's only one of it, so modifying it in one place affects all references to that object (just like any object). This is generally considered a benefit since it makes modules like colors possible. It shouldn't be necessary protect modules from changes made to global prototypes, since those changes should only be extensions. If your, or someone else's, modules are modifying built-in methods/properties, then that's probably bad practice in the first place.

Although you didn't give an example, I would think you probably want to either create local functions (not attached to the prototype), or look into using inheritance to solve your concerns with specific objects.
