As far as I'm concerned, this is just syntactic sugar. I've noticed that
elm has a convention to use the last parameter in a function where an OO
programmer would use this. Using this convention, code winds up being very
similar when used.
OO version:
model
.getSomeProperty
.withDefault(3)
Elm version:
model
|> getSomeProperty
|> Maybe.withDefault 3
