digitalmars.D.bugs - [Issue 20819] New: std.getopt should detect duplicated pointers


          Issue ID: 20819
           Summary: std.getopt should detect duplicated pointers passed as
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos

import std.getop;

    auto optparser = getopt(
      "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.
