I don't think this is a bug. A flag can't both simultaneously accept a value and be a countable switch AFAIK.

Thanks for the fast response. I could readily accept that, when you put it like that, but it does seem to work in the Python implementation.
See here - not allowed both, but works when you delete one or other.
Of course, the python implementation (and by extension the online thing) differ in not having serde build a struct of args and flags.
So I suppose it's really a question for you & team whether it should be allowed or not.
If I may advocate for my desired behaviour: I'd say it's consistent with:
-q --quiet Be quiet.
implying that either flag can be used and be accessible on Args#<either>
.
Supporting it would of course mean that it'd only work for integer value flags; not a mix of countable switch and string flag, for example.
Feel free to close if not something you want to support, understood.
