Implementations
Languages that support multiple inheritance include: C++, Common Lisp (via Common Lisp Object System (CLOS)), EuLisp (via The EuLisp Object System TELOS), Curl, Dylan, Eiffel, Logtalk, Object REXX, Scala (via use of mixin classes), OCaml, Perl, Perl 6, Python, and Tcl (via Incremental Tcl (Incr Tcl)).
Some object-oriented languages, such as C#, Java, and Ruby implement single inheritance, although protocols, or interfaces, provide some of the functionality of true multiple inheritance.
PHP uses traits classes to inherit multiple functions.
