title: lodash flow and multiple arguments
body: <p>I have 2 functions that I will add in a lodash flow:</p>
  
  <pre><code>function normalizedFormFields(fields) { // needs only 1 argument
      return _.mapValues( fields, function( value ) {
          return { 'content': value };
      } );
  }
  
  function mergedModelAndFormFieldss(model, normalizedFormFields) {
      return _.merge( {}, model, normalizedFormFields )
  }
  
  const execution = _.flow( normalizedFormFields, mergedModelAndFormFieldss )
  
  const errorMessageBag = function( fields, model ) {
      return execution( fields, model ) // initiate flow with 2 arguments
  }
  </code></pre>
  
  <p>As you can see the first function normalizedFormFields takes one argument. The second one needs 2: the value returned from the previous function (which is the normal behavior of flow), and another one: model.</p>
  
  <p>But in the errorMessageBag invocation, I launch the flow process with 2 arguments. How to have the second argument, available to the second function in addition to the returned product of first function ?
  As you see the problem is that the first function in the flow takes and need only one argument. Is this a kind of situation where "curry" should come into play ? Please illustrate.</p>
