Minimum PHP Version?

[Tyblitz]

Ouch. I knew that there were hosts out there still running 5.2. I was hoping they would be in the severe minority.

It's a damn shame, because a lot of the engineering-based problems that you alluded to in the Hello World topic could be tempered with the tools in 5.3+. Anonymous functions and namespaces alone would help greatly with global scoping in the core and for plugin developers, and neither of these features can be shimmed/polyfilled by client code.

My reply to helloworld plugin was before I saw this thread... +1 to it though.
Another possible solution is dropping PHP 5.2 support in a 4.X beta version parallell to dev in the 'main' version (I remember Modx had Evolution & Revolution series with this type of strategy)
