Fixes #4474, where lookup() calls fail out the entire interpolation when the provided key value is not found in the map. This will allow using coalesce() along with lookup() to greatly improve module flexibility.
Add specifics about using the optional third argument for providing a default value.

This should fix #4474 in which lookup() calls fail and short-circuit the entire interpolation when the given key is not found in the map. This allows an optional third argument for providing a default value when the key does not exist in the map, which will allow better composition of lookup() with coalesce() et al.
