Use std.algorithm:equal for range compare with approxEqual for

Thinking of trying to do the next project in D rather than Rust, but…
Rust has built in unit testing on a module basis. D has this so no

These are automatically build and run along with all unit tests as part

Well, can't do. I need this purely at compile time, and
