type Field a = Lens' Config a

Fields that can be modified with all lens machinery.

customVariable :: YiConfigVariable a => Field a

Accessor for any YiConfigVariable, to be used by modules defining YiConfigVariables. Such modules should provide a custom-named field. For instance, take the following hypothetical YiConfigVariable:

@newtype UserName = UserName { unUserName :: String } deriving(Typeable, Binary, Default) instance YiConfigVariable UserName

$(nameDeriveAccessors ''UserName (n -> Just (n ++ "A")))

userName :: Field String userName = unUserNameA . customVariable@

Here, the hypothetical library would provide the field userName to be used in preference to customVariable.
