Given
data Expression = ExpToken String | ExpAnd Expression Expression
How to write an attoparsec parser that parses this example:
"a" and "b" and "c"

ExpAnd (ExpToken "a") (ExpAnd (ExpToken "b") (ExpToken "c"))?
Consider using sepBy1 to obtain ["a", "b", "c"] first. Then you're just a foldr away.
