Looks like PHP developers have rejected the idea of metaprogramming, at least with runkit ever making it to the core of PHP. This is too bad, but hey at least I was courageous enough to actually write a feature request ticket to PHP, and someone took the time and trouble to respond. XD
Perhaps I should try namespace wildcard import next time? Although the chance of each feature request gets approved is low, there is a fair chance for at least one of all those requests being accepted if all of them reach PHP developers.
