It's worse than I thought, really out of the question for 5.x. 

Though I still think it's something we should consider for 6.0 as it's something we need to fix in the long term (and 6.0 already has breaks, such as strings used in binary operations need to be changed to binary strings). 

I can provide a short PHP script which can automatically fix the case of internal classes and keywords like array() in most source code out there.

We can test such automated porting scripts on samples collected from PEAR, Google Code and projects like Drupal, Joomla etc. to reduce side effects.

Regards, Stan Vassilev

Is that to any move to case sensitivity? Even if it is the tidiest way of 
plugging some of the holes in a clean UTF8 implementation via 6.0 where 
'lower' or 'upper' may produce different results?

Personally I've always worked with maintaining case - C++ dictates it - so 
it's natural to ensure that a case-sensitive search always provides the 
correct results. I'll even correct code that differs ....
