Global functions

Are global functions declared with block or global scope. ie. declared 
in the block object or var object?

Consider:

package {
    {
        function fun() {
            print("1");
        }
        fun()
    }
    {
        function fun() {
            print("2")
        }
        fun()
    }
}


This prints

2
2

in the RI.

So should functions be treated like var declarations or as let 
declarations. Seems like they are like vars in the RI.

Is this right?

I don't see how they could be anything else for ES3 compatibility's
sake. At least, within a single compilation unit.

I was under the impression that for the function definitions to be confined to a block scope, you had to define them as such (with let function statements), like so:

package {
    {
        let function fun() {
            print("1");
        }
        fun()
    }
    {
        let function fun() {
            print("2")
        }
        fun()
    }
}

I'm unsure if this currently works in the RI, or not.

While this compiles in the RI, it still produces 2 and 2 for the output.

ie. doesn't seem they are block scoped functions either.

I believe "let function" is broken in the RI (it has been in the past).

I encouraged Michael to file a trac ticket, and he did:

http://bugs.ecmascript.org/ticket/337

Anyone else who finds an RI bug and can't see a report of it in the  
existing tickets, feel free to run it by this list and file if it's  
not known -- or just file and we'll dup it in due course. These  
tickets will be fixed. Anyone who wants to help hack on the RI,  
please contact me. Thanks,
