Pipeline mixin for underscore/lodash. Takes a seed as an initial value and any number of functions as parameters. The seed value is passed to the first function, and the return value of each function is passed as the parameter to the next.

Pipeline

_.mixin({
    pipeline: function (seed) {
        return _.rest(_.toArray(arguments)).reduce(function (l, r) {
            return r(l);
        }, seed);
    }
});

Example:

_.pipeline([1,1,2,2,3,3,4,4], _.uniq, _.rest, _.first) // 2
