When I looked up the word hail in Longman Online Dictionary and Oxford Advanced Dictionary Online, I saw it has been marked as transitive verb. I also noticed by someone's note that a verb followed by a preposition is not be categorized as transitive verb. For example in:
I came to his home
=> come is still intransitive verb.
So could you point out to me the role of as in the example below:
The conference was hailed as a great success.
