A short introduction to `maybe_expr` in Erlang
I am a huge fan of functional programming and recently discovered the maybe expression in Erlang. In the blog post I show an example of code I refactored recently using maybe, how to enable the expression in OTP 25 (and up), and compare it to a language feature in Haskell (ExceptT).

Awesome, thanks for the info! I am very hopeful to start writing more of my Erlang journeys.
