Exactly, that alone makes it far more useful/portable in practice than a lot of other languages for this type of thing. A python file can have a shebang, but it'll need a bunch of other files around it for module references, etc. Not to mention initialization/setup, etc.

The fact that dependencies are referenced in the file and automatically handled at runtime (first or repeated) is a really nice feature to have... it's expressly why I started using Deno over other options for this.
