Property access syntax causes massive performance drop

[Athari]

Your competitor here. 😀

I've run performance tests on YaLinqo, Ginq and Pinq. Whenever I use property access syntax, performance of Ginq queries drops 2-5 times. See gist with performance results (results from YaLinqo master branch). You should cache functions or something. Using "string lambdas" in YaLinqo, which rely on create_function, does decrease performance, but not so significantly (since I've added caching, inner queries stopped killing performance too).

Just curious, is using explicit iterator classes instead of generators a deliberate design decision, or do you just aim for compatibility with older PHP versions?

P. S. Thanks for competition. Ginq and Pinq forced me to finally update my library: add missing methods, improve performance, add integration with continuous integration and code quality tools, put reference documentation online etc. 😀
