Benefits
References increase flexibility in where objects can be stored, how they are allocated, and how they are passed between areas of code. As long as one can access a reference to the data, one can access the data through it, and the data itself need not be moved. They also make sharing of data between different code areas easier; each keeps a reference to it.
The mechanism of references, if varying in implementation, is a fundamental programming language feature common to nearly all modern programming languages. Even some languages that support no direct use of references have some internal or implicit use. For example, the call by reference calling convention can be implemented with either explicit or implicit use of references.

Famous quotes containing the word benefits:
“When your parents are in political life, you aren’t normal. Everybody talks about the benefits, but I don’t know what the benefits are.... But I’d rather have that kind of mother than an overweight housewife.”
—Katherine Berman Mariano (b. 1957)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
“It is with benefits as with injuries in this respect, that we do not so much weigh the accidental good or evil they do us, as that which they were designed to do us.—That is, we consider no part of them so much as their intention.”
—Laurence Sterne (1713–1768)
