how will that more stack data into ram? If the delegate gets an array of 
pointers to stack frames (or objects) then what you get is a copy of the 
pointers that still point into the stack (or objects). If what you have is 
a slice of the stack, then what about the next function out? you will either 
still have a reference to another stack frame, or won't have access to it 
at all. You might get something with a void[][], but then you need to do 
an alloc on each delegate creation, not to mention Gregor's issue.
