Add obstacle for monkey-patching

@rosenfeld Hi there :wave: and welcome!

Absolutely. Which tool for communication you were thinking of?

I read the “feeling alone” last week when somebody shared it on Reddit. A great read :clap:

Yes I spotted it long time ago: Remove monkey-patching? · Issue #936 · mikel/mail · GitHub
But we kept mail because it’s a solid lib, we didn’t wanted to implement a lib from scratch just because of monkey-patching. Of course I’m extremely happy they removed it from the lib.
