Do other languages have similar ArrayAccess features as PHP?

Long story short, there is a PHP feature called ArrayAccess which allows you to overload the [] operator (among other things I think) for your class, so you could have a custom class MyClass implements ArrayAccess of which $myVariable is an Instance, and do stuff like

$myVariable[]=6;

or $someVar=$myVariable[78];

After you've defined what it'll behave like.

I find this feature rather rather elegant and useful and would like to know whether this is possible in other programming languages.

Thank you!

Python supports it too, by implementing the "magic" methods __getitem__ and __setitem__.

With them you can even support slicing like obj[i:j].

C++ supports this in operator overloading.

Most .Net languages support this in indexers.
