Yep, all my timesheet, invoicing, financial analysis, reporting and more 
at work is all written using 5.6.2. There is a *lot* of code.

I have an open ticket to upgrade stuff to 5.8 (which I suppose I should 
update to 5.10 thereby leap-frogging a generation), but until some 
showstopper comes along (e.g. a new must-must-must-have module that 
doesn't work) then it's never going to happen.

Then again, I know how to deal with the issues involved to upgrade, or 
more likely, work around any eventual 5.6 issues that may arise from 
here on out. In that case I wouldn't file a bug report for fear of 
ridicule :)

Now why does that strike a chord?
