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.

Famous quotes containing the words level of, level and/or access:
“Preschoolers sound much brighter and more knowledgeable than they really are, which is why so many parents and grandparents are so sure their progeny are gifted and super-bright. Because children’s questions sound so mature and sophisticated, we are tempted to answer them at a level of abstraction far beyond the child’s level of comprehension. That is a temptation we should resist.”
—David Elkind (20th century)
“Architecture might be more sportive and varied if every man built his own house, but it would not be the art and science that we have made it; and while every woman prepares food for her own family, cooking can never rise beyond the level of the amateur’s work.”
—Charlotte Perkins Gilman (1860–1935)
“Knowledge in the form of an informational commodity indispensable to productive power is already, and will continue to be, a major—perhaps the major—stake in the worldwide competition for power. It is conceivable that the nation-states will one day fight for control of information, just as they battled in the past for control over territory, and afterwards for control over access to and exploitation of raw materials and cheap labor.”
—Jean François Lyotard (b. 1924)
