Level of Access
Everything in Smalltalk-80 is available for modification from within a running program. This means that, for example, the IDE can be changed in a running system without restarting it. In some implementations, the syntax of the language or the garbage collection implementation can also be changed on the fly. Even the statement true become: false is valid in Smalltalk, although executing it is not recommended. When used judiciously, this level of flexibility allows for one of the shortest required times for new code to enter a production system.
