>There is no "map" function, but there are "List.map", "Dict.map", "Array.map" among others, and none of them are related to one another. This is not only annoying, but also breaks the abstract data-type guarantee: our call-sites are now tightly coupled to our implementation details. If I decide to change from a "List a" to an "Array a" for efficiency reasons, my whole codebase needs to know about it.

I can accept this in old languages. I can accept this in embedded languages. I cannot accept this in a language that is supposed to be about programmer productivity.

Basically this patient has one bullet hole in their heart. One. This doesn't make the patient dead as the author seems to let you think.
