I was excited when I heard aboutimport type as I've been using dynamic imports on a component to save start up time in vscode for some time, however it's very fragile as I only want to import types and not implementation.

When I try to put theimport type guard in place I get the following error though:

What's happening here is I'm wanting to import anexport class definition and only reference it as a type by getting its constructor withtypeof. However I'm getting an error that it's being used as a value inside a: type definition?
