Description

An Option can have a type (e.g. String, Number, ...) but this type can not automatically be inferred later since Option is not generic.

It would be usefull to add a generic to the Option so the type can be inferred like Option<String>, Option<Number> and so on.
The CommandLine can then have an

<T> getParsedOptionValue(Option<T> opt)

method so type-safe fetching of Option values is possible without any (optimistic) casting or typechecking is involved.
