Just look at the file quotations.fs in the development version, it's already 
implemented ;-).  There has been some discussion about the name, and as { } 
are already used for locals, we ended up with [: and ;] to start and end 
quotations.

It's slightly more work, as we want to have a separate locals scope inside the 
quotation - we can't access the outer locals, as we don't know when the 
quotation is executed.
