In the associated issue you said using ErrorCall is fine. And calling error is the same as throwing ErrorCall according to https://www.stackage.org/haddock/lts-19.5/base-4.15.1.0/Control-Exception.html#t:ErrorCall. What am I missing?

I have only documented the "non-empty list"-requirement in the docs for
waitAnyandwaitAnyCatch. I have refrained from adding it to the docs forwaitAnyCancel,waitAnyCatchCancel,waitAnySTM, andwaitAnyCatchSTMsince the docs for these functions refer to eitherwaitAnyorwaitAnyCatch.Closes #130
