Add method to peek last item in queue about queue HOT 5 CLOSED

Hello,

thanks for your interest about Queue library.

I did not have to deal with such behavior since the creation of the library, but it happened in the past.
I would even extend this enhancement to the whole queue by creating a method like peek_rec to peek any record in the queue (as you may also have to search in the whole queue for a duplicate record and making more sense for a LIFO implementation).

I think I could add a peek_previous() method as inline to do exactly what you want (for FIFO implementation).

I could also implement a method to drop any item in the queue, just because more peeking options would exist, but as I would like to keep the library straightforward and fluent as possible, I wouldn't plan to add these drop methods, only peeking on all records would be possible.

What do you think about it?

Thanks for giving thoughts about improving this library!

Changes made and exemples added...

Thanks for your thoughts/needs about enhancing this library, I (on behalf) of open source community thank you for it!

Just one thing before closing the issue, I would be really enjoying that you would test the changes and see if it fits your needs (using peekPrevious method) before tagging this new version...

Thanks a lot for the idea to improve this tiny library, making it more flexible to ones needs!
Really appreciated, kind regards,

Thank you for the fast reply, and the generic implementation. I am going to test it and report back ASAP. Just please give me a few days. Thanks again for your work.

Tested, and seems fine, closing the issue. Thanks for your patience.
