Will Fancher 86a8212cd8 Added Members Constraint ... The Members type family (closed) takes two type-level lists, m and r, as parameters. m contains the effect labels which should be members of r. The resulting type is a constraint requiring that all elements of m be members of r. This simplifies constraints that require multiple members of the same effect list. For example. ioState :: (Member IO r, Member (State Int) r) => Eff r () becomes ioState :: Members '[IO, State Int] r => Eff r () Furthermore, it allows apps to easily define their typical effect constraints alongside the typical runtime effect. type AppEffs = '[State Int, Writer String, IO] type AppConstraint r = Members AppEffs r type RunApp = Eff AppEffs		2016-02-07 06:37:45 -05:00
