(very good) to create a very fast D version, using whatever
tricks it has to maximize performance.
I would like to include in my paper a good comparison of
various implementations in different compiled languages (C/C++,
D, Nim, etc) to show how it performs with each.
I looked into your NIM code and from programmers point of view
there is nothing interesting going on. Simple data structures and
simple operations. If you wrote equivalent code in C, C++, D,
NIM, Rust, Zig and compiled with same optimizing compiler (llvm
or gcc) you should get the same machine code and almost the same
performance (less than 1% difference due to runtime). If you got
different machine code for equivalent implementation then you
should file a bug report.
The only way you will get different performance is by changing
implementation details but then you would compare apples to
oranges.
