https://issues.dlang.org/show_bug.cgi?id=19335 Issue ID: 19335 Summary: std.getopt: make it an error to have options that differ only by case when case insensitive Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: dhasenan gmail.com void main(string[] args) { import std.getopt; import std.stdio; int a, A; getopt(args, "a", &a, "A", &A); writefln("a=%s, A=%s", a, A); } Compile, run with `-a 5 -A 10`. The expected result is an exception saying that option `A|a` is multiply defined, hopefully also mentioning that the case-sensitive flag exists. The actual result is that `a` is set twice and `A` is not set. This exception should also trigger when you define an argument named `H`. (I would also argue that case-insensitive is a terrible default, but that's unlikely to change.) --
