Hash uses eql? but rbtree uses == for searching

[cjheath]

rbtree does not drop-in as a replacement for Hash as easily as it ought to because it uses == for equality testing instead of eql?, for example here: https://github.com/pwnall/rbtree-pure/blob/master/lib/rbtree/tree.rb#L196

Granted you need to use <=>, but there's no good reason not to use eql?

Any update on this? 18 months have passed and the issue has not even been acknowledged.

@cjheath Sorry for the lack of responsiveness. There's not much I can do without a failing test, and I don't have the time to look into that right now. Do you think you could help me by getting a failing test? Ideally, it would be in rbtree's testing suite as well.

Thank you!

Can do - but not today. I'll try to get to it this week. In fact I'll be happy to fix the problem and send a PR, if you are willing to accept that?
