Yes, but 'eval' has the semantics "run this code but don't let it play
any funny tricks on me, like dying or anything", where 'do {...} while'
has the semantics "a while loop that evaluates its condition at the
end".  There's no obvious reason why 'return' should behave
differently in a 'do while' loop than it does in a 'while' loop.

However, if you want to make return behave differently in 'do {...};'
versus 'do {...} while ...;' I wouldn't object too strenuously; I just
think it would be confusing.
