Improve the conversion of Callable to a string

[mspirkov]

Fix: #256

@jaapio After that, I want to test how it works on a few Yii packages. Do you have any other ideas for improvements?

[jaapio]

Not right now. When needed we can always create a V3. But I think we are on the right track now to support generics. I will try to implement this in phpDocumentor and the more downstream libraries.

Maybe someday, it would be good to have a conversation about what you would need extra in yii. I would like to hear why yii has its own tool. And what it does.

Maybe we can find each other in a slack or discord?

Then I'll check tomorrow to see if everything is working properly and let you know!

I found something else that needs to be corrected/added. I'll do it today.
