Criticism
It has been argued that one should eschew the use of the explicit return statement except at the textual end of a subroutine, considering that, when it is used to "return early", it may suffer from the same sort of readability problems that are claimed to exist for the GOTO statement. For instance, that in later development, a return statement could be overlooked by a developer, and an action which should be performed at the end of a subroutine (e.g.: a trace statement) might not be performed in all cases. Conversely, it can be argued that using the return statement is worthwhile when the alternative is more convoluted code, harming readability. Languages without a return statement, such as standard Pascal don't have this readability problem.
Some early implementations of languages such as the original Pascal and C restricted the types that can be returned by a function (e.g. not supporting record or struct types) to simplify their compilers.

Famous quotes containing the word criticism:
“Parents sometimes feel that if they don’t criticize their child, their child will never learn. Criticism doesn’t make people want to change; it makes them defensive.”
—Laurence Steinberg (20th century)
“The aim of all commentary on art now should be to make works of art—and, by analogy, our own experience—more, rather than less, real to us. The function of criticism should be to show how it is what it is, even that it is what it is, rather than to show what it means.”
—Susan Sontag (b. 1933)
“The greater the decrease in the social significance of an art form, the sharper the distinction between criticism and enjoyment by the public. The conventional is uncritically enjoyed, and the truly new is criticized with aversion.”
—Walter Benjamin (1892–1940)
