Extend the Maybe to an Either, or an Result<T, E>, that carries either the result or the error information and you have the same thing. Add some syntactic sugar to either get the success result or propagate the error (under the condition that the current function returns a Result and there is a way to cast the inner error type into the outer error type) and you have a nice alternative to try/catch that can entirely replace it
