Lots of `Deprecated` warning in the current version of PHP.

Hi, I'm trying out the package today, and I was wondering: Is it still maintained?
Upon installing it, I received the following warnings:

If it is abandoned, what are some good alternatives you would recommend?

[ragboyjr]

mmm, I wouldn't say abandoned..., but I don't have any need to update it. But feel free to make a PR for adjustments.

Thanks for getting back!
I already went with a different library since I needed to move forward.

Just as a heads-up: currying is coming to PHP 8.6.

Given that the idiomatic approach is about to change, it might be best to hold off on major updates, as the idiomatic shift could render the library redundant or deprecated.
