subhosting to run user scripts

I want to allow users to run arbitrary scripts, but they don't need to be available as endpoints, so they don't need

Deno.serve(() => { .. etc. };

Deno.serve(() => { .. etc. };

... Is there a way to allow users (a la subhosting) to upload a simple script like

return 4+5

return 4+5

and get a response with the return value and console logs?
