Anthony,

Most code that is run in Smalltalk is in methods which belong to =
classes. The canonical way of printing out the class and method =
invloved is Class>>method. When you evaluate code in a workspace, it =
isn't really a method and doesn't really belong to a particular class, =
but to keep various programming/debugging tools happy, it is made to =
appear so temporarily. The code gets compiled into a method named #DoIt =
in the class UndefinedObject (the class of which nil is the only =
instance) and then gets deleted once it is complete.

Cheers,
Bob
