In the past, this was deprecated from JavaScript. For example, see: 

  http://developer.netscape.com:80/docs/manuals/js/core/jsref/function.htm


Recently - see bug 65683, also bug 68557 - support for function.caller
was added back. Also, function.arguments.callee is now supported. 
We are about to publish (today!) the tarball for JS1.5 pre-release 3,
containing these changes.


However,function.arguments.caller does not seem to be currently implemented.
cc'ing Brendan in case of any misunderstanding on my part. 


Does this bug raise a valid point?

[Brendan Eich [:brendan]]

Neither arguments.caller nor function.caller is ECMA-standard.  arguments.caller
is potentially exploitable in security attacks.  We aren't going to restore it,
IE/JScript does not support it, so I am marking this bug WONTFIX.
