Hi
I don't know what your getout plan was but when I'm in this situation I do the following (hopefully listing this trick will help the OP):
I have headNote, fromJustNote, fromJustDefault, lookupJust, lookupJustNote, tailNote - a whole set of functions which take an extra note parameter - or for the example of lookupJust still give a crash, but have both the thing you were searching for and the list of things you were searching in - lookupJust requires a Show, so can usually tell you roughly where you are. I also always write it out as Module.Name.function - since line 5 has a habit of being moved to a different line a lot more than names changes. And because I am used to this, maybe 95% of all unsafe functions are already in Note form, so I just change the new ones I added since last time I broke down and cried. However, its useful, but hacky. Its not something I should have to do manually. Thanks Neil
