Eliminates binding boilerplate for your custom types in routes and forms
(i.e. no need to define QueryStringBindable, PathBindable, and Formatter bindings).
If your custom type is a value class (or has a single value constructor),
play-iso will automatically convert primitive type for a given route or form field param
to the target custom type (e.g. convert a Long to a UserId).
Given the sheer amount of boilerplate required for a single
custom type
in a route like GET /user/:id controllers.User.show(id: UserId), it's untenable to, say,
model database primary/foreign key relationships as custom types in a Play application (100 database tables? good luck).
The previous link does not even include the additional binding boilerplate required for Form fields
(e.g. mapping("id" -> of[UserId])).
This is unfortunate as Play users will often avoid custom types due to the (manual) work required. With play-iso you get custom type bindings for free ;-)
