So now, each time a new version of a library pops up you need to 
search-replace the version number for all your source code, and source 
code of other library you depend on? This is insane.

The version number shouldn't be there, except perhaps if it's a 'major' 
version number full of breaking changes.

Also, putting in the source code the location or protocol to fetch the 
repository isn't much better. There's a reason we have a module import 
path: so that finding external code depends on compile-time 
configuration, not on the actual code you build.

Allowing URLs in the import path might be an interesting idea though.
