It's not possible to make a view of a [non thread local variable declared as
var](https://nim-lang.github.io/Nim/manual_experimental.html#view-types). So
the following code doesn't compile:
{.experimental: "views".}
var someArray = [0]
proc main() =
let viewOfArray: openArray[int] = someArray
main()
Run
/usercode/in.nim(6, 37) Error: cannot borrow from someArray, it is not a
path expression; see
https://nim-lang.github.io/Nim/manual_experimental.html#view-types-algorithm-path-expressions
for details
Run
But there's a workaround:
{.experimental: "views".}
var someArray = [0]
proc takeOpenArray(arr: openArray[int]) =
let viewOfView: openArray[int] = arr
proc main() =
takeOpenArray someArray
main()
Run
1. Why is this not allowed? The manual doesn't explain it. (also the link in
the error message both doesn't work and why it doesn't work is described in a
different section)
2. Is my workaround just an oversight? And if yes how will it be prevented,
will the creation of the view with the call already be an error?
