The question of stack frames is actually really complex. Whether it's  
worth adding additional calling depth (Felix's proposal adds a single  
frame, my proposed changes would add one more) in order to simplify  
readability and maintainability really depends on a number of factors.  
Without knowing how deep the stack is at the point that Fetch/Store  
Proc is called, how many variables the callers have allocated on the  
stack, and how tight we are for headroom already, we're not going to  
know whether this is safe or not.

But I still maintain, from a pure elegance perspective, that  
abstraction layers that meander across multiple concepts are untidy.
