Project mention: The Monad Invasion - Part 2: Monads in Action! | dev.to | 2024-02-27

Previously, we built an Optional and showed an existing set based on Language-Ext, but various libraries also offer Monad implementations. In the case of our SDK, we deliberately avoided relying on external libraries like Language-Ext. Indeed, Monads are a part of the SDK's public API, and relying on an external library would introduce a dependency over which we would have limited control.
