Url: #991


Right now the only way to define custom DQL functions is by giving the class name, and Doctrine will create the class:

$config->addCustomNumericFunction('FOO', 'My\Custom\DqlFunction');

This is very limiting when the custom functions has dependencies, for example it can't be created by a DI container.

The approach I have taken here is very simple: it allows to define a callback instead of the class name: the callback will be called and it should return the instance:

$config->addCustomNumericFunction('FOO', function($funcName) {
    return new My\Custom\DqlFunction($funcName);

On a side note, I think it would be great to generalize that approach because currently there are a lot of places where the same constraints apply.
