Add properties to function while in function with out specifying function ?

[Richard A. DeVenezia]

I can add a property to a function while in the function

function foo () {
foo.X=1;
}
alert (foo.X) // undef
foo()
alert (foo.X) //1

or

function foo (name,value) {
foo [name] = value
}
foo ('A',1)
alert (foo.A) // 1

how would I add a property to currently running function without naming the
function ?

self doesn't work
function foo (name,value) {
self [name] = value
}
foo ('A',1)
alert (foo.A)
alert (self['A'])



function foo ( name, value ) {
**something** [name] = value
}
foo ('X',9)
alert (foo.X) // want 9

What would **something** be ?

function foo ( name, value ) {
foo[name] = value
}

I found what I was looking for.

function foo (name,value) {
var callee = arguments.calle e
callee[name] = value
}
foo ('X', 9)
alert (foo.X)

presumed to be the same as
[color=blue]
> function foo ( name, value ) {
> foo[name] = value
> }[/color]

but not needing to know the function name at source writing time.

Ideally yes, but IE has a bug which frustrates that pattern, requiring instead

foo = function () {
foo.X = 1;
};

Which version of IE is that, and what is the bug?
It would sound like it prevents function declarations from declaring
recursive functions.
