DIAGNOSTICS

Error: cannot create a $type to add this to my collection.
    Some options are specified to create a $type object, which is native to this collection. However, for some reason this failed. Cast by addRole()

Error: cannot load collection module for $type ($class): $@
    Either the specified $type does not exist, or that module named $class returns compilation errors. If the type as specified in the warning is not the name of a package, you specified a nickname which was not defined. Maybe you forgot the 'require' the package which defines the nickname. Cast by addCollection()

Error: cannot rename $from into $to: already exists.
    Cast by renameRole()

Error: cannot rename $from into $to: doesn't exist.
    Cast by renameRole()

Error: class $package does not implement method $method.
    Fatal error: the specific $package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package. Cast by notImplemented()

Error: invalid collection $name.
    The collection with $name does not exist and can not be created. Cast by add()

Error: this $object is not a collection.
    Cast by addCollection()

Error: wrong type of role for $collection: requires a $expect but got a $type.
    Each $collection groups sets of roles of one specific type ($expect). You cannot add objects of a different $type. Cast by addRole()
