*If* you can locate one example, you may be able to manually examine the compiled method itself to see what distinguishes it in terms of the reference to a missing object. e.g. what's in the literal pool for a method which references a non-existent class? You could create one such example explicitly and then use what you�� learn from that to track down the real ones.

VW has a MethodCollector class which allows a variety of selection options for methods, including an arbitrary block of clode. I don't know if Pharo has something comparable. Worst case scenario, you use a poor mon's approach. It is easy enough to enumerate all classes and traverse their class and instance methods. That would pretty much be what you would want from a MethodCollector anyway when using an arbitrary block for selection.

VW also has an Undeclared namespace. I know Pharo doesn't have namespaces, per se, but it may still track undeclared references in some manner.

Tim,��
Another anomaly��I found with the above, even with my code that does not reference the missing classes - but is contained within the same package of classes that do reference the missing classes (clear?)... my application crashes with an error that the reference could not be found. This may be something introduced after build #913 - where I wasn't getting these errors... and by build #1258 they appeared (may have also appeared earlier, but I don't recall).��

I had hoped to use the allReferences you listed above, but I had to run through all my classes and methods to find missing classes - the methods are highlighted, but lots of methods are highlighted for various reasons.�� When I found the offending methods - I had to "comment out" the references to get the method to then save... most of these were maintenance methods that are only still around for reference/documentation... I need to find another way :)

It sure would be good to be able to see ANY missing references in one call so I could run that periodically to keep things clean.��

Hi - I was convinced in earlier Pharo��s, if you had a code reference to a non existent class you could find it by searching for references to its symbol name eg #MyMissingClass allReferences (or find references in the UI). This doesn��t seem to work in Pharo 11?�� I loaded a package with a missing class, and when running something it complained about the missing class (it was an announcement), but I couldn't find an easy way to find it in my code to correct it? I ended up creating the fake class to then find references to it (as I then had a class), which seems way over the top?

I haven't had a chance to try this in Pharo 12, but shouldn't what I have done work? Or is there some new way to do this? I asked on Discord users, but didn't get a reply other than it rang a bell.

I know there has been a lot of work in the area of how things are represented and I wonder if something has got broken by mistake?
