import std.getop;
auto optparser = getopt(
args,
std.getopt.config.passThrough,
std.getopt.config.caseSensitive,
....,
"iterations_min", "A iterations minimum (default: " ~
to!string(iterations_min) ~ ")", &iterations_min,
"iterations_max", "A iterations maximum (default: " ~
to!string(iterations_max) ~ ")", &iterations_min,
);
Spot the error.
It should be detected by the getopt automatically and throw an exception
without even checking the 'args'. I really doubt there is a valid use case to
have duplicated pointers, and if there is (i.e. renaming flags and deprecating
but supporting old one), it can be enabled using std.getopt.config flag.
