Hi there, at Piwik we also experience this issue. We are trying to optimise the algorithms and data structure of the leading open analytics platform. After making the refactor to have some of our objects use the ArrayObject feature (see, we were hit by this bug which prevents us from debugging the code. Because we cannot debug the data structures (as explained in this issue), we decided not to implement the change for now, which prevents us from massive performance improvements.

That is to say we would love to have this feature in Xdebug :) Thank you for your consideration.

Btw we would be happy to sponsor the work to get it done, if this is a possibility (I've also emailed Derick to ask)
