Some time ago, Charles Foster had the idea that all bound variables should be added to the stack trace whenever an error occurs [1]; would that be helpful? Before implementing this, however, we would need to think of various issues related to performance (try/catch statements will get slower when variables are bound to the stack every time; large XML snippets that will not be garbage-colected when being bound to an error; database references are not available anymore when an error is raised, etc.).
