Editing Operator overloading (section)

===1980s===
[[Ada (programming language)|Ada]] supports overloading of operators from its inception, with the publication of the Ada 83 language standard. However, the language designers chose to preclude the definition of new operators. Only extant operators in the language may be overloaded, by defining new functions with identifiers such as "+", "*", "&" etc. Subsequent revisions of the language (in 1995 and 2005) maintain the restriction to overloading of extant operators.

In [[C++]], operator overloading is more refined than in [[ALGOL 68]].<ref>{{cite web |title=A History of C++: 1979−1991 |url=http://www.stroustrup.com/hopl2.pdf |last=Stroustrup |first=Bjarne |author-link=Bjarne Stroustrup |page=12 |access-date=1 April 2007}}</ref>
