Hello Nick. Sorry maybe I came in thread late. I disagree, std.getopt has 7 options and a few syntax. many options are "no" for other options. If I understand what super dan write, I think he has a good points. There is repeat a little but it is small price for simplicity of library. And I disagree when you said that just wrap class {} around variables is not important. it is very important. more types should not add without necessity. I have some variable in main() that I parse and maybe few globals. Why put they all in a class? It is not wanted complexity not justified.

Also the modular part is not good argument. Code to handle command line is unique, never called from the app. Only once. Should be there in line. Design for modular there is not justified. I think even is mistake. Parse arguments is simple problem and should have simple solution. std.getopt is simple solution. (only one function!) All other are complicated. It means they did not see how simple problem is. Thank you, Dee Girl
