I am reading this over and over... "a == b is a boolean". I know what you mean but it may be confusing to other users so I will clarify. It is a boolean when a and b have values, else it is just an expression. In dal, "a==b" is a query (an expression) that is evaluated on every record and if it returns true the record is selected (not unlike SQL).
So in db(a == b).select() or the proposed (a==b).select() (a==b) does not return a boolean.
