Use new keywords

[drupol]

Motivation

There are multiple goals behind this PR.

First, is to get rid of AbstractOperation. Its sole purpose is to provide the static method of, which is just syntactic sugar.
Syntactic sugar is cool, but it's not needed in Collection. We could gain some performance by completely removing them.

Then, by removing it and instantiating operation using new could also be a good thing for static analysis and types inference.

Note

When dealing with methods having the @pure annotation, using the keyword new to create operation will trigger an ImpureFunctionCall in PSalm.

However, when having nested functions in those methods, using the new keyword, will not trigger an ImpureFunctionCall in PSalm.

This PR:

• Use the new keyword instead of using the static method of().
• PSalm score is now 97% 🎉

Nice 👍 . I like the idea of this.

All looks good except for the Unpack changes. Perhaps you could leave those for a separate PR and address the comment?
