Objects,Modules and Packages

• Lives in its own namespace
• Package methods can be exported or called directly
  • Foo->bar()
  • (if Foo exports it)

• A module is a file containing one or more packages

• An object is a ed reference to a hash
  • It doesn't have to be a hash reference,but it's most common.
• Blessing assigns a single class to an object
• An object can be re-blessed
• You can muck with the internals,but that doesn't mean you should

• Modules must end with a true value
• Packages don't have the same restriction
