One possibility to keep ignored events out of your update and - incidentally - encourage some more reuse, is to move the decision into the decoder:
update
mouseLeftClick : Json.Decoder Position mouseLeftClick = Json.field "button" Json.int |> Json.andThen (\button -> if button == 2 then fail "I'm ignored!" else Mouse.position )
The gist is that if an event-decoder fails, the event just happens but no message is sent to Elm.
Thanks Ilias! That is much cleaner. A better expression of the intention as well. I'll update our code :)
