Very good :-) First suggestions: - Generally compile your D code using the -w switch (you have missing some overrides and more things) - Add a main() with some benchmarking examples to your program, so I will have something to optimize for. - Use the -profile compiler switch on the benchmarking examples to see what's slow. - Use final classes or final methods where possible and keep an eye on memory allocations. Consider using structs in some places instead of classes. - Keep in mind that ~ and ~= in arrays isn't a very fast operation. In some cases an Appender helps, and in some cases some workaround may be needed. See you later, bearophile
