In the world of Elixir programming, there are numerous features and syntactic constructs that contribute to the language's elegance and expressiveness. One such hidden gem is the concept of "implicit try".
The macro mechanism in Elixir is not only an interesting metaprogramming feature - in fact, it is at the language's very core. And the more awesome fact is that, using macros, you can override the algorithm of defining functions itself!
So you don’t know what’s the type of struct you’re passing somewhere? Maybe it can be one of few types and you have to distinguish them? Or any other reason… But it’s about checking the struct type. Just use one of the coolest Elixir features - pattern matching!
