I'm creating a DI container extension. It's too experimental to be bundled with PHP itself, so I'm thinking of releasing it with PECL or PIE.

Although I have only done rough measurements, it was about 10 times faster than Laravel's DI.
This saves the overhead of using reflection classes, so it is expected to be faster than DI using reflection classes.
It takes twice as long as the regular "new class" version, but we are currently revising the design to see if we can make it even faster.
