Multiple declarations of ... about co4 HOT 2 CLOSED

in the picture hanging example, this function gives this error in CO4 compilation

Because tails is already defined in CO4's prelude. I fixed Hang.hs. I just added inits to the prelude as well and changed Hang.hs accordingly.

I would like to add Hang.hs to CO4's test suite (https://github.com/apunktbau/co4/blob/master/test/CO4/Test.hs) in order to run it while cabal testing. To do so, Hang.result must result in value IO (Maybe a) and Hang.hs may not be a standalone Mainmodule (because it needs to be imported from Test.hs). Is that ok for you if I change Hang.hs accordingly or do you need it to be a standalone module?

from co4.

sure, go ahead with the changes.
