{{alias}}( ...fcn )
    Returns a pipeline function.

    Starting from the left, the pipeline function evaluates each function and
    passes the result as the first argument of the next function. The result of
    the rightmost function is the result of the whole.

    The last argument for each provided function is a `next` callback which
    should be invoked upon function completion. The callback accepts two
    arguments:

    - `error`: error argument
    - `result`: function result

    If a provided function calls the `next` callback with a truthy `error`
    argument, the pipeline function suspends execution and immediately calls the
    `done` callback for subsequent `error` handling.

    Execution is *not* guaranteed to be asynchronous. To guarantee asynchrony,
    wrap the `done` callback in a function which either executes at the end of
    the current stack (e.g., `nextTick`) or during a subsequent turn of the
    event loop (e.g., `setImmediate`, `setTimeout`).

    Only the leftmost function is explicitly permitted to accept multiple
    arguments. All other functions are evaluated as binary functions.

    The function will throw if provided fewer than two input arguments.

    Parameters
    ----------
    fcn: ...Function
        Functions to evaluate in sequential order.

    Returns
    -------
    out: Function
        Pipeline function.

    Examples
    --------
    > function a( x, next ) {
    ...    setTimeout( onTimeout, 0 );
    ...    function onTimeout() {
    ...        next( null, 2*x );
    ...    }
    ... };
    > function b( x, next ) {
    ...    setTimeout( onTimeout, 0 );
    ...    function onTimeout() {
    ...        next( null, x+3 );
    ...    }
    ... };
    > function c( x, next ) {
    ...    setTimeout( onTimeout, 0 );
    ...    function onTimeout() {
    ...        next( null, x/5 );
    ...    }
    ... };
    > var f = {{alias}}( a, b, c );
    > function done( error, result ) {
    ...    if ( error ) {
    ...        throw error;
    ...    }
    ...    console.log( result );
    ... };
    > f( 6, done )
    3
