Indeed, being able to introduce a short name for the current module, or having a fixed short name like 'This' or 'Self' would be neat.
The standard workaround for your example would be
import Prelude hiding (length,null)
That won't work though, because what I failed to mention is that I needed this (while avoiding CPP) to cope with external modules growing their exports lists, such as Data.Foldable starting to export 'length' and 'null' in base-4.8.0.0 Moreover, hiding a non-existent symbol is a warning in recent GHC's but a hard error in older GHCs, so that's not an option either if you want to avoid CPP, support GHCs back to 7.0, and be -Werror-clean. More generally, 'hiding'-imports aren't robust in terms of forward-compatibility.
Did you try a .hs-boot file with your self-import trick?
