-/// There are two principle ways to refer to things:
-///   - by their locatinon (module in foo/bar/baz.rs at line 42)
-///   - by their numeric id (module `ModuleId(42)`)
-///
-/// The first one is more powerful (you can actually find the thing in question
-/// by id), but the second one is so much more compact.
-///
-/// `Loc2IdMap` allows us to have a cake an eat it as well: by maintaining a
-/// bidirectional mapping between positional and numeric ids, we can use compact
-/// representation wich still allows us to get the actual item
