You have implemented your own type-checker, right? I plan to add a 
type-checker to our live-sequencer project. [1] So far I have thought 
about using the Helium type checker but I have not done it so far. If you 
want to make your type-checker useful for other projects, you may put it 
into a separate package without the hard to install dependencies on cairo 
and glib.
