That's not been my experience. Whenever I have mentioned the lack of arrays/vectors in the past I have been inundated with Elixir devotees asking me why I need them when Elixir has maps with numeric keys at which point I just throw up my hands in despair.
Not denying it. Every community has bad apples.
It's not charitable to make assumptions for the entire community -- or the tech stack itself -- based on them however.
Seems like you've been chatting with the wrong people. A lot of the ElixirForum regulars -- me included -- are very practical and realistic folk who use several languages all the time.
Contrary to what you and others try and insinuate, we are very aware that the language is not a universal tech.
So yet again, you guys are smacking at a strawman that's very easy to beat. It's quite tiring to argue with stuff that I never said (and most of Elixir's community haven't said it either). But I think I'll give up for now. :)
