When you design a framework or a library in an implementation language, you need to play to the rules of the game. While implementing a library for a functional language, you need to design functions that are referentially transparent, side-effect-free and easily composable with the existing platform. Similarly for an object oriented implementation, there are well-published idioms and design patterns (factories, builders etc.) that the language espouses, which your contracts need to honor. e.g. designing a module in a statically typed language like Java, you need to design abstractions based on interfaces that can be easily injected using dependency injection.
