This PR removes the hack in CLI that allows to run scripts with shorthand: deno script.ts. Removing this functionality because it hacks around short-comings of clap our CLI parser. We agree that this shorthand syntax is desirable, but it needs to be rethinked and reimplemented. For 1.0 we should go with conservative approach that is correct.
