[plt-scheme] current-eval is now ready to receive anything...

Hi all,

By preparing current-eval to receive more than just syntax-objects as
stated in docs (which I quoted in my last post but mis-interpreted)
can I know before hand which things may be passed to current-eval
besides what the user types in and their type?
My guess is that when the user types something it is sent in the form
of syntax object to current-eval, except the s-expr
