Brendan Hansknecht (Mar 17 2023 at 14:38):What is the list of?
Currently we have no display type feature for converting a list to a string. We do have dbg if you just want a short live debug print out.
In general, map the list element type to a string. Then join it together with commas or similar.
For numbers could do List map Num.toStr |> Str.joinwith ", " |> Stdout.Line
itmuckel (Mar 17 2023 at 14:43):perfect, that did it, thanks! Also is there no variable shadowing in roc? I had a global list l and then I had a function with an l parameter and that collided somewhow.
── DUPLICATE NAME ─────────────────────────────────────────────────── test.roc ─
The l name is first defined here:
7│ l = [1, 2, 3, 4, 5]
^
But then it's defined a second time here:
16│ walk = \l ->
^
Since these variables have the same name, it's easy to use the wrong
one by accident. Give one of them a new name.

Yeah, no shadowing at all in roc. Have to change the name of one of them
