with "-replace"  It tries to detect "-rtrue" or "-rfalse", which is the short option + the boolean value for it. The ConvError is then caused by "to!bool("eplace")".

I'm not sure if this report is valid but it's still possible to throw a better exception with "expected true or false following simple option" or something like that.

Maybe you can change the report title. "Better error message for short option followed by wrong bool string".... + set it as enhancement, assuming you'd agree that the real problem is that of course.

Now I found it in the documentation: > If the option has a parameter, that must be "stuck" to the option without any intervening space or "=" But it is not the reason why the issue was created. Main reason is that behavoiur is different for "-help" (built-in option) and "-replace" (custom option). --
