I can download the package and run 'cabal install' inside the package

Hi Conor
Chuan-kai Lin uses 'effect basis' in the ICFP paper on the Unimo
monads, otherwise I've seen 'operations' used. I'm on the fence for
'effect basis' vs. 'non-proper morphisms', but biased against
'operations' (as its not sufficiently characteristic).
Best wishes

I uploaded a small library [1] for generating VCD files [2], which can
be viewed with waveform tools like GTKWave [3]. Though VCD is
commonly associated with Verilog simulation, at Eaton we use it to
visualize vehicle data in realtime: data is pulled off the CAN bus,
formated to VCD, then piped

Sorry to interject a noob comment, and maybe I am not understanding
