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

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! [1] https://mail.haskell.org/pipermail/beginners/2016-December/017276.html
