Cannot read property 'ctor' of undefined

[Hurtak]

The following code compiles and throws runtime error Uncaught TypeError: Cannot read property 'ctor' of undefined
It should not compile since I am referencing non-existing variable

Mimimal example code:

import Html exposing (text)

main =
    (List.foldl (\current aggregated -> 
        let
            newAggregated = 
                current :: newAggregated -- typo here, was supposed to be aggregated
        in
            newAggregated
    ) [] [1, 2, 3]) |> toString |> text

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.
