            Bug ID: 171041
           Summary: Cannot declare a let variable twice: 'e'
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: macOS 10.12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: rob at stutton.net

I wouldn't write code like this (below) myself, but it was emitted by the minifier and so my app doesn't work in Safari, or Safari TP.
The code looks legal to me ...

let e = e => {
    for (let e of [1, 2, 3]) // Cannot declare a let variable twice: 'e'.
