Ability to examine a non-executing namespace

Using `m`, it's possible to jump to a given module, but there's no way to look at its namespace, either in the variables view, or in the `!` terminal. Is this possible? It would be also nice to be able to get at functions namespaces in those module, though that's not as important. This way, I could examine some global variables easier.

And by the way, unless this is trivial to implement, it's not really high priority.
