Subj : [Rhino] can you add default getters/setters?

This would better go into the wishlist newsgroup ;)

In ASP i can write
    Session("key") = "val";

And it expands to
    Session.Value("key", "val");
where Value is a setter of type propput (or propputref), in IDL slang.
There is also a getter for Value, so you can write
    str = Session("key") which expands to Session.Value("key").

Would that be doable in Rhino, so I can supply a getter like
    Object Session.jsGetDefault_Value(String key)
and a setter
    jsSetDefault_Value(String key, Object val)
to be used by the runtime?

For this particular construction, the runtime introspection would have to
check first if the object (Session) is an instanceof Callable (by the way,
now it checks if it is instanceof Function when encountering the call
operator, is it necessary?).
If it is a Callable, then the call ("key") will be applied to the object. If
is not, then the runtime can look for default setters/getters and use them
if a match is found.

There are the ADO.Recordset - like scenarios too. For example
    var str = rs("field");
expanding to (written with the prefix proposed above)
    var str =
rs.getDefault_Fields().getDefault_Item("field").getDefault_Value();

Comments?
