Background

C++17's std::string_view

We like std::string_view. It gives us type erasure and efficiency at the same time.

  var value_holder;
  var params;
  var func;

  // empty Generator - no value contained

var func = fun(){
  var ret = 0;

// async takes a 0 parameter function object which is run asynchronously and 
// returns a Boxed_Value (ie, any value, including void, should work)
