Description

def result is incorrect when using the for loop without explicit call of .items or .pairs.

import std/tables

let t = initTable[string, int]()
for key, value in t:
  discard value

let r = 0 .. 2
for value in r:
  discard value

let s = @[1, 2, 3]
for value in s:
  discard value

let str = "hello"
for value in str:
  discard value
