One thing that surprised me about nix when I started using it is that there
isn't a way to say, "I need package X with version Y".  Instead, you have
to resort to having multiple definitions of the package with different
package names for different versions.  This seems a bit hacky to me.  As
mentioned in a separate reply, I expect to have several such packages and
being able to specify it that way would make things much easier.
