Short version:
Fix old bugs, don't add new ones.
Long version:
I'm a bit surprised by the amount of new language constructs recently requested on the internals list.
First of all, I should note that none of these requests are supported by patches, so I call them
gimme's. "
Gimme that feature from language X, I used it once and it's just awesome!!!1111", you know. Quite useless.
Second, people seem to forget the fact that new features do not appear in older versions automagically after they're added into HEAD and old installations tend to live
forever very long. So even
if this feature does eventually get into the core, for quite a long time you would be able to use it only on your own server because your hosting provider uses good old PHP 4.3.4 (or even PHP3, see
this) and is not going to update it because this may break other customers phpBB's.
So here is the new "feature" I would like propose myself: let's make all the existing things working as they should instead of adding a bunch of new features used by a couple of hackers.
If you're bored and have an itch to hack something, take a look at
bugs.php.net, I'm sure you'll find it quite entertaining.
