is there a set container?

[Adam D. Ruppe via Digitalmars-d-learn]

The std.container.RedBlackTree is close:

Or you may prefer my work-in-progress unofficial docs:

http://dpldocs.info/experimental-docs/std.container.rbtree.RedBlackTree.html

You can see methods there like insert, removeKey, and 
opBinaryRight, which is actually the in operator:

to see if an element exists in the set.


Create a red black tree with this convenience function:
