I have installed simonster’s Memoize package. Recently a new Memoize package was introduced, which I would like to try out. How to do this correctly? The problem is that  
both packages have the same name and therefore I fear that something gets confused.

This isn’t going to work well. Package names (and module names) really have to be unique across a Julia install. I hope the author of the new package renames it.

In meanwhile, if you really want to try it out, you’ll have to delete the old package from your `.julia`, and then `clone` the new package. You can do this if the old Memoize package does not have any dependants within your installed packages.

In case someone stumbles upon this. Easiest way without a hassle is to download the package, rename it and use it.
