Ok, so that means there’s nothing to be done for now, I just have to wait ?

Some other small questions, not directly related:

I’m using leksah to edit code. How do I:

- Browse the source of reactive-banana from leksah ? I would like to check for instance how the Applicative of Behaviour is implemented.
- Is it possible to check the type of statements from the gui ?
- Is it possible to pull up the documentation of a function directly from the gui ?
- Is it possible to to the definition of a function, including the ones in other packages (like the ones of reactive-banana) directly from the gui ?

thanks !
