In Luau, consider using a variable for a type to be a usage of it

[Dekkonot]

At the moment, this produces an unused variable lint:

local foo = require(script.bar)

local baz: foo.quux

Ideally, it would consider the use of foo in the type annotation to be a valid use of it.

I'm doing this because a project I'm using has very large type definitions, and it's horrible to have them in the same file as the bulk of my code, so I split it. This ends up leaving me with a module that's only used for type definitions though. It makes me sad to have to manually suppress this lint.
