destructuring syntax to bind them to local variables. As a convenience, the RegexMatch object implements iterator methods that pass through to the captures field, so you can destructure the match object directly: The value on the right should be an iterator (see Iteration interface) at least as long as the number of variables on the left (any excess elements of the iterator are ignored). This can be used to return variables: julia> y, x = x, y (5, 6) julia> x 6 julia> y 5 If only a subset of the elements of the iterator are required, a common convention is to assign ignored elements to a variable consisting of only
