title: Reactive variables as query parameters
body: <p>After implementing apollo-client into my react app, I noticed that a lot of input data will probably end up in a reactive variable somewhere. And if I want to request anything to the server, often, the value will come from a reactive variable. So it would simplify my code a lot if I could link the value of the reactive variable to the parameters of my query. Ideally, what I would want is something like this:</p>
  <pre><code>gql`
  query FirstName {
    firstName @client
  }
  query LastName {
    lastName @client
  }
  
  query user($firstName: ???, $lastName: ???){
    user(firstName: $firstName, lastName: $lastName){
      id
      firstName
      lastName
      address
      dob
    }
  }
  `
  </code></pre>
  <p>Now, I understand that these requests would resolve in parallel, so the above would never work... But, how do I <em>make</em> it work? Do I need to add loadash just for this? Is there an apollo-client solution for this? How would I solve this with loadash or any other library?</p>
