[Haskell-cafe] Netwire woes: creating a wire with mkGen_

[Francesco Ariis]

Hello -cafe,
    a few days ago I posted this [1] in beginners, I'll pester you
too before giving up.

tl;dr: I want to create a wire which outputs a stream of 'q's when the
letter Q is pressed and a stream of 'a' when the letter A is pressed.
What I wrote is not working and I suspect I am not using mkGen_ correctly.

Any pointers appreciated!
