Thanks for paying attention to an important detail on the design
criteria.

As this is a binding to allow Rust programs to access the feature
implemented and offered by Git, I fully agree that reimplementing
what Git does in an incompatible way in Rust would not help the
targetted intended audiences at all (that is better off done in a
project that aims to reimplement what Git does, like gitoxide,
targetting native Rust solution).

If I were not paying attention, I would very likely have missed the
misparses of number-as-bool, distracted and blinded by the prettier
and nicer syntax the language offers over the original in C X-<.

Thanks.
