Yeah. I've been aware of that one forever. There's a line in my TODO.md about it already. It may date back to the origins of TODO.md, even. :-)

Cool. Let me know what you think about setByParse being a table vs. a seq[(paramName, unparsedValue)]. I am kind of leaning toward the latter with a provided in/contains operator if Nim can't do string in seq[(string,T)] already.

It would be even nicer to go all the way to seq[(paramName, parsedValueVariant)], but I don't think we could use variants and still let CLI authors add their own types via custom argParse/argHelp definitions. Though I did my best to do enums/sets/seqs/etc., I'm sure there will be a need for custom types. Maybe I'm missing something about some kind of "Any" type or some other approach in Nim, though. Very open to ideas.
