If you want to send different messages to the same object, where the
message itself is a parameter, you can use `perform' (or, if the
arguments are not objects, you can use FCall). Imagine you wanted
to set a filter function on some data stream or have the user set a
step routine, etc.

You can have many such displays writing to a raster.
