Does gleam let me destructure a list so that I can bind the head and body each to a variable?
e.g. in f#
let splitHeadAndTail = function
| h :: [] -> printfn "got head and EMPTY tail"
| h :: t -> printfn "got head and tail"
| [] -> printfn "got empty list"
The example in their docs does a 1:1 map and doesn't show if you can bind the whole tail[1]
It'd be kind of silly to create a greenfield BEAM language that doesn't expose one of the most fundamental operations you can do in BEAM bytecode, and that every list-processing function ultimately relies upon :)

Agree, which is why i was confused it wasn't in the tour I linked to in the Lists or Destructuring sections
Why not just use Haskell? You don't get OTP/Beam, but the GHC runtime provides almost all the same functionality (plus a lot more), to the point where the Cloud Haskell library is basically a full clone of Erlang's actor functionality.
