 you misread me: What I meant is that exising code would be negativly
 affected by using closures with a WP PHP requirement of below 5.3 as of
 today and for the next 3-4(?) years.

 As written this ticket is highly theoretical. When 5.3 is minimum system
 requirement than every coder can actually use cosures because of the
 system requirements. I just do not see a need for a ticket here but maybe
 you can shed some light onto this. To showcase something in the future? I
 mean this trac is about the core code, right? Otherwise I could open
 tickets that showcase the possibilities we get with PHP 5 regarding
 objects, visibility and inheritance, exceptions and interfaces - something
 infact I already use in plugins w/o boosting the requirements too much.
