Why the partial function case (a,Some(b)) => (a,b) inside the collect doesn't trigger MatchError if there is None value in one of parameters?

that's how collect method works it takes only elements on which the function is defined. See isDefinedAt

@suud belated a comment, sorry :) Note collect takes only elements that match a defined case; as a partial function it defines, it needs not all cases be covered, namely for instance case _ may be ommitted.
