A symbol bound to each item in the collection in turn.
A form which is evaluated to yield a COM
i-dispatch interface pointer that implements the collection protocol.
A form to be evaluated.
Note that for collections whose items are interface pointers, the forms must arrange for each pointer to be released when no longer needed. The collection should be a COM interface pointer for an
i-dispatch interface that implements the Collection protocol. The items are converted to Lisp as specified in Data conversion when calling Automation methods.
