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.
