Editing Operator overloading (section)

===2000s===
Microsoft added operator overloading to [[C Sharp (programming language)|C#]] in 2001 and to [[Visual Basic .NET]] in 2003.

[[Scala (programming language)|Scala]] treats all operators as methods and thus allows operator overloading by proxy.

In [[Raku (programming language)|Raku]], the definition of all operators is delegated to lexical functions, and so, using function definitions, operators can be overloaded or new operators added. For example, the function defined in the [[Rakudo]] source for incrementing a Date object with "+" is:

<syntaxhighlight lang="perl6">
multi infix:<+>(Date:D $d, Int:D $x) {
    Date.new-from-daycount($d.daycount + $x)
}
</syntaxhighlight>

Since "multi" was used, the function gets added to the list of [[multidispatch]] candidates, and "+" is only overloaded for the case where the type constraints in the function signature are met.
While the capacity for overloading includes '''+''', '''*''', '''>=''', the [[Imaginary unit|postfix and term '''i''']], and so on, it also allows for overloading various brace operators: "'''['''x, y''']'''", "x'''['''y''']'''", "x'''{''y''}'''", and "x'''('''y''')'''".

[[Kotlin (programming language)|Kotlin]] has supported operator overloading since its creation.
