Do you mean a new `StackFrameContext::getCFGElement()` member function? I agree. I can do it, however this technology where we get the block and the index separately is used at many places in the code, then it would be appropriate to refactor all these places. Even wrose is the backward direction, where we look for the CFG element of a statement: we find the block from `CFGStmtMap` and then we search for the index **liearly**, instrad of storing it in the map as well!!!
