Added "access" to use the arrow operator.

I get that (*a).b and a->b are the same, but the second one just feels better to me.

This PR adds in a access function that works the same as field except it uses an arrow instead of a period.

Please tell me if you feel that this should be renamed, but also feel free to not merge this PR.

Hi, thanks for taking the time to put this together!

The path generator is meant to be used for pointers, and mixed paths: (path a > b) Or: (path a > b . c), where c is a field of b.

It might still be convenient to have access for single/nested pointer accesses, but I don't know if it should be a generator or a macro in "user space" that outputs path for you.

Hi, thanks for looking over this PR.

I missed path when I was searching for a way to do that, thanks for letting me know.

I'm going to leave this PR open because of your last comment, but feel free to close it.

Thank you.

I improved the documentation a bit to describe path.
