Thanks all for the responses.
For:
"Maybe.map doesn't appear useful as record updates aren't compose-able?)"
I'll reformulate the question: What is the most factored version of the
following code?
update msg model =
case msg of
ToggleDone id ->
let
updateEntry t =
case t of
Nothing ->
Nothing
Just t ->
Just { t | done = not t.done }
in
{ model | entries = Dict.update id updateEntry
model.entries }
UpdateTaskName id newTaskName ->
let
updateEntry t =
case t of
Nothing ->
Nothing
Just t ->
Just { t | name = newTaskName }
in
{ model | entries = Dict.update id updateEntry
model.entries }
