Criticism
Late binding has poorer performance than an early bound method call. Under most implementations the correct method address must be looked up by name with each call, requiring relatively expensive dictionary search and possibly overload resolution logic.
Late binding necessarily prevents the use of static type checking. When making a late bound call, the compiler has to assume that the method exists. This means a simple spelling error can cause a runtime error to be thrown. The exact exception varies by language, but it is usually named something like "Method Not Found" or "Method Missing".
Late binding prevents many forms of static analysis needed by an integrated development environment (IDE). For example, an IDE's "go to definition" feature cannot be used on a late-bound call, because the IDE has no way to know which class the call may refer to. Another problem is that the lack of typing information prevents the creation of dependency graphs. However, other programming methods such as abstract interfaces can result in the same problems.

Famous quotes containing the word criticism:
“The critic lives at second hand. He writes about. The poem, the novel, or the play must be given to him; criticism exists by the grace of other men’s genius. By virtue of style, criticism can itself become literature. But usually this occurs only when the writer is acting as critic of his own work or as outrider to his own poetics, when the criticism of Coleridge is work in progress or that of T.S. Eliot propaganda.”
—George Steiner (b. 1929)
“I consider criticism merely a preliminary excitement, a statement of things a writer has to clear up in his own head sometime or other, probably antecedent to writing; of no value unless it come to fruit in the created work later.”
—Ezra Pound (1885–1972)
“I am opposed to writing about the private lives of living authors and psychoanalyzing them while they are alive. Criticism is getting all mixed up with a combination of the Junior F.B.I.- men, discards from Freud and Jung and a sort of Columnist peep- hole and missing laundry list school.... Every young English professor sees gold in them dirty sheets now. Imagine what they can do with the soiled sheets of four legal beds by the same writer and you can see why their tongues are slavering.”
—Ernest Hemingway (1899–1961)
