To "define" a class nothing is required (you must write
"source" code in a piece of paper/aTextFile).
If you want to create an object (like a class) you need
to DO something, ... e.g. send a message.
Working with OOLanguages, only definition is possible
(an required), because execution is not allowed when
you are "there"; a computer/machive will do the work
later in time (evading object creation if possible :-( ).
It is like writing a letter to God, talking about ideal objects...
Working IN smalltalk, computation/production is a side
effect of a working environment. When you are in the
environment, you must do(evaluate) actions and create
classes/species (if it is possible at the moment of evaluation).
It is like working in real world.
The "doIt" instead of "defineIt" has important implications
in systems development/creation.
Is is not a good/bad idea; it is a requirement to send
messages. It is possible becasue the receiver is near your
fingers and at the same time.
Building open systems (instead of closed/ideal systems)
let you lower the risks of working declarativelly.
hope this help,
Ale.
