Please don't just say it's useful, please say why :)
dl() has absolutely nothing over loading in php.ini, and has many drawbacks.

By the way, if it's really important, we can look into supporting it.
The way it was before - it worked in most cases (assuming you never
tried to use a class before you dl() the corresponding extension), but
could result in crashes in other cases.

I don't think it's very important, though.  dl() should most probably
be deprecated from the language, as it's not supported in thread safe
mode, it's slow and insecure.  It also creates a host of interesting
bugs/buglets that are difficult to hunt and fix.  Other than that -
it's great :)


Uhm, are you suggesting we take away the possibility of loading
extensions at run-time?


Depending on which run-time you mean, yes.  I don't think it should be
possible to load extensions from within a PHP script.

Note that dl() never really behaved properly.  It was always broken to one
degree or another.  Also, it'll be completely unavailable in the thread
safe version of PHP, so we might as well deprecate it completely.
Loading extensions in the php.ini file is still very much possible.
