Dear all,

I've written about implementing binary search trees: https://pharokeepers.github.io/pharo/2019/07/07/SmiljanaBinarySearchTreeinPharo.html

Feedback and opinions is always welcome :)

pay attention to the formatting of your code.

It makes is difficult to read (I do not know if this is wordpress effect or not).

Once you have your tree implementation and tests I would really like to see if you can get another implementation and measure

the impact of introducing a NullNode to remove all the isNil checks.
