They don't /own/ Prism. They merely license it, so what the Oxygene
developers do and what the Delphi developers do are two different things.

If I remember correctly we already have something similar somewhere among
our supplied units for quite some time.

In the end I suppose that support for that TParallel class will be based on
"patches welcome" once anonymous functions are supported.
