In the module declaration for Task there is a 'where':
effect module Task where { command = MyCmd } exposing
with MyCmd later declared to be a type:
type MyCmd msg =
T (Task Never msg)
then later we see command used like a function:
perform onFail onSuccess task = command (T (map onSuccess task `onError` \x
-> succeed (onFail x)))
can someone explain what is going on here? I can't find any documentation
on the use of 'where' in a module declaration.
