Regardless of the outcome of the type issue, this code is doing blocking io inside a go block, which should be avoided. Consider using `thread` and `loop`, which would also likely work around the type hinting issue because it would avoid the state machine transform. The code already using the blocking version of channel put (>!!) which shouldn't be used inside a go block, but is fine for use outside of it.
