• 'extends' is recommended over use base because use base pushes on the end of @ISA and extends replaces @ISA
• This is important to ensure that classes which do not have super-classes still properly inherit from Moose::Object
• the 'default' key specifies a default value
• references must be wrapped in a code ref but any value can be wrapped in a code ref
• default can be augmented by the 'lazy' keyword, It only sets value when called by the reader method
• lazy => 1 # if lazy is used, a default must be present
