Hello, I need some clarification on the following: Using a unified stack model for wam (ie. choice points and environments on same stack) I can understand why the current environment may not be at the top of the stack, by being burried under at least one choice point. However, using the split stack model (ie. environments and ch. points reside on different stacks) how can the current environment not be at the top of the environment stack? Which are the cases that give rise to such situation? I' d appreciate any comments. Thanks in advance, Vassilios E. Axaris SUNY@Buffalo Computer Engineering.
