Additional Comments

This issue seems related to or possible the same as this other closed issue: #3263

It would be easy to convert the structure from an object to an array as a workaround, but pug should handle both

The code above fails with the following error:

   var err = new Error(fullMessage);
              ^

Error: Pug:4:32
    2| p Offerings
    3|
  > 4| each offering, key in offerings
--------------------------------------^
    5|   h2= offering.title
    6|   p= offering.description
    7|   p= offering.price

The value variable for each must either be a valid identifier (e.g. `item`) or a pair of identifiers in square brackets (e.g. `[key, value]`).
