title: Adding elements to an STL Map in a constructors Initialization List?
body: <p>I was wondering if this was possible, and if so how I'd go about doing so.  If it's not possible I'll just have to add the elements during the constructor body.</p>
  
  <p>Ideally I would like the map immutable after construction.</p>
  
  <p>What I'm trying to achieve is adding two pairs to the map that are created from constructor parameters.</p>
