Perhaps you could do:

     import { Function1, Function2} from "https://deno.land/x/oak/mod.ts";

In the file that needs them? Though then you have a lot of redundant URLs everywhere and god knows how auto-imports could work.

Or perhaps you could do

    // deps/oak.ts

     export * from "https://deno.land/x/oak/mod.ts";

and then you'd do

    import { Function1, Function2 } from './deps/oak';

I am not a fan of any of these.
