Somewhat non-intuitive flag conversion to semantic type

[JakeWharton]

I have a --debug flag and rather than litter my codebase with conditionals on a boolean I want to have this return Debug.Console when set and otherwise have a default of Debug.Disabled. As far as I can tell, this isn't supported by flag().

I first looked at mutuallyExclusiveOptions(option("--debug").convert { Debug.Console }).default(Debug.Disabled), but this fails to compile as at least two options are required.

Thankfully I found option().switch<Debug>(mapOf("--debug" to Debug.Console)).default(Debug.Disabled), although it took a while.

Is it worth putting a convert extension onto FlagOption?
