Not in a statically typed language, please! It should be a compile-time error to try and set the key `Kye`.

I agree with the compile-time error checking part, but it's possible to have groups of key/value pairs (i.e. anonymous records) in a statically typed language where only specific keys are allowed, with specific value types for each key.
