Unnecessary Warning

[Roba1993]

From my perspective the following warning is not really valid?

warning: Warning
   ┌─ script:51:9
   │

   │ ╭───────────────────────'
48 │ │     let top = #{};
49 │ │     let bottom = #{};
50 │ │ 
51 │ │     for (i, (k, v)) in causes.iter().enumerate() {
   │ │         ^^^^^^^^^^^ Pattern might panic

   │ ╰─' In this context
   │  
   = Hint: Rewrite to:
     if (i, (k, v)) {
         // ..
     }
