Hello.
I recently reinstalled Windows 10 (build 1903), and downloaded
DMD (v2.087.1) and dub (v1.16.0).
My project no longer compiles, giving the following errors:

Hello.
I want to create a tree which maps sequences of numbers to data.
ex:

I have no prior knowledge of what makes a good tree, and I am
unsure if what I've got is good. I mean it works, but if anyone
