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:
“Adults understandably assume that the level of verbal proficiency a five-year-old displays represents his level of proficiency in all areas of functioning—if he talks like an adult, he must think and feel like one. However, five-year-olds,... belie the promise of adult-like behavior with their child-like, impulsive actions.”
—Dorothy H. Cohen (20th century)
“There are old heads in the world who cannot help me by their example or advice to live worthily and satisfactorily to myself; but I believe that it is in my power to elevate myself this very hour above the common level of my life.”
—Henry David Thoreau (1817–1862)
“Oh, the holiness of always being the injured party. The historically oppressed can find not only sanctity but safety in the state of victimization. When access to a better life has been denied often enough, and successfully enough, one can use the rejection as an excuse to cease all efforts. After all, one reckons, “they” don’t want me, “they” accept their own mediocrity and refuse my best, “they” don’t deserve me.”
—Maya Angelou (b. 1928)
