Would be cool if there was a platform independent way in D to 
construct a sequence of "call" instructions in memory. Then it 
would be possible to write a JIT compiler in the exact same style 
as that example.

It would be relatively easy to add to phobos although you'd have 
to be careful about DEP. Hmm, perhaps I will try writing 
something like this...
