You can actually invoke functions as parameters via backtick directly. So the following actually works:
left ᐊ = str => str + 'left';
return ᐊ`
{
"thing": true
}`;
If you don't want to use a special symbol it might be nice to call it dd or something really short. Then you can just say:
import { dd } from 'dentist';
const str = dd`
