Why the PHP min 5.2 in this example?

In PHP 5.3 has been added support for the anonymous function and WordPress minimum requirement is PHP 5.2.
If you want create a plugin for WordPress that have a big support need to support PHP 5.2.

PS: I use Debian Sid for the development, PHP 5.6 RC3. Yeah! Yes i like the development version, and i have never noticed about this minimum requirement of WordPress until someone opened a ticket.
