I have a feeling that the original bug was from a time where we generally thought this side of commandline infrastructure was going to become a more broadly used way of building commandline tools with rich commandline interfaces. However, in recent years the project has gravitated towards the infrastructure in the `Option` library which is used by both Clang and LLD.

So, I'm personally not inclined to add more complexity to the commandline parsing logic. Is there a particular need that motivated this? I understand you wanted a `float` option, but for what purpose? Generally, we've been successful using basic integer ratios for debugging and testing options.
