## Design Notes
This demonstrates the basic design of hosts: Roc code gets compiled into a pure
function (in this case, a thunk that always returns `"Hello, World!"`) and
function (in this case, a thunk that always returns `"Hello, World!\n"`) and
then the host calls that function. Fundamentally, that's the whole idea! The host
might not even have a `main` - it could be a library, a plugin, anything.
Everything else is built on this basic "hosts calling linked pure functions" design.
