Referential Transparency
Absence of side effects is necessary but not sufficient for referential transparency. Referential transparency means that an expression (such as a function call) can be replaced with its value; this requires that the expression has no side effects and is pure (always returns the same results on the same input).

Famous quotes containing the word transparency:
““End of tomorrow.
Don’t try to start the car or look deeper
Into the eternal wimpling of the sky: luster
On luster, transparency floated onto the topmost layer
Until the whole thing overflows like a silver
Wedding cake or Christmas tree, in a cascade of tears.””
—John Ashbery (b. 1927)
