The method valueOf() of a Drop does not await promises

[thomas-jakemeyn]

Use Case

I put an object on the scope of the template - let's call it o - and I would like to make it super easy for template authors to serialize it to a string representation. What I have in mind is to call my serialization function from the method valueOf() of my Drop, which would provide the following authoring experience:

# Returns the identifier of the object
{{ o.id }}

# Returns a string representation of the object
{{ o }}

Problem

The problem is that my serialization function is async and, instead of getting the string representation, I get [object Promise]. That behavior is different than e.g. liquidMethodMissing() that awaits promises.

Makes sense. Let’s see what we can do.
