Julian Hyde commented on CALCITE-2296:
--------------------------------------

Can you make this issue more concrete by giving an example query and what it would simplify to?

Thanks for the reference to the code. I hate TODOs in code. So, now you've logged the bug, if you're in that code for another reason, remove the TODO.
