Well said, static types save cost in the long run, they can help set the programmers intentions with the right invariant’s. I love writing elixir, but i always have that weird feeling that I wrote something wrong somewhere, that will comeback to bite me maybe not now, maybe in a few weeks, years etc ofc BEAM idiom of let it crash, does mitigate a bit of the worries but it is still a far cry from something like rust were you can guarantee things hold in most cases & you don’t need to write insane conditionals just to make sure some input is the right type
