Switch Handler to an interface.

HandlerFunc is much better as a function returning a Handler, rather
than a newtype for the function type itself. This way there is no
confusion creating a type-inferenced variable with HandlerFunc(func(...
and then using a HandlerFunc where a Handler is expected. Much better to
only have one public type.
