I agree with all the arguments for sticking with status quo though I’m too lazy to upvote them all, lol.
From what I gather, Elixir’s update syntax isn’t even equivalent to Erlang’s := since it can update multiple keys in one go. If the insert one were to stay consistent with the update syntax, what would it look like? It sort of feels weird to give several keys to insert then raise if some already exist, no? Maybe not. This feels to more of ditching => and := altogether a new class of “update multiple keys if they all exist” syntax.
I personally really don’t care about inconsistencies if it (arguably) improves clarity. Like send/receive in Elixir are both prefix functions whereas one is infix and the other is prefix in Erlang.
