--- Comment #2 from hsteoh at quickfur.ath.cx ---
The "standard" solution is to create a struct that encapsulates possible
configurations of getopt, and pass that as an optional first parameter:

    module std.getopt;
    struct GetoptConfig {
        dchar optionChar = ...
        string endOfOptions = ...;
        ... // etc.
    }

    module myprogram;
    void main(string[] args) {
        GetoptConfig cfg;
        cfg.endOfOptions = ...;
        cfg.getopt(args, ...);
    }

But this will break existing code, though.
