"Late-binding" isn't the issue with closures on a loop

Lua also has late-binding closures, as can be seen here: https://repl.it/repls/HotpinkEagerQuery (the first one intentionally misused to highlight the difference between block scope and function scope)

It just also has block scope. That's the thing python doesn't have, thus causing the confusion.

Block scope is better emulated with nested functions, such as:

for i in range(5):
  def block_scope_emulation(i):
    def thing(x):
      return x*i
  block_scope_emulation(i)

找到指南中解釋迴圈內閉包的段落，並將其措辭與連結的 Lua 範例以及 issue 中的巢狀函式範例進行比較。完成的標準是，解釋能夠區分延遲繫結和區塊作用域，並準確描述 Python 的行為。
