Description
let mut key = key.to_lowercase()
Because I see that ENV is forced to be lowercased here, if my struct is renamed to uppercase and underscored, the ENV parsing will fail consistently.
I tried using convert_case(config::Case::Upper) but it fails if there is an underscore. Now in order to support env, I have to make it all lowercase and underlined.

Research direction
Read src/env.rs at the linked conversion around line 260, then inspect how convert_case(config::Case::Upper) handles underscores. Reproduce the reported environment-variable parsing failure and determine the expected uppercase, underscored form; done means the requested case conversion works for environment keys without breaking existing behavior.
