Multiple definitions of same key shows no error

Hey, thanks for this crate! 🙏

When moving one of my project to use it, I added the same key twice by accident. Obviously the end result of what was displayed was not as expected 😓

I don't know how feasible it is, but it would be awesome if this could be caught at compile time with a clear message :)

In some times we may need to override a key, so this can't add any warning.

Couldn't it be an option? If not big deal
