After messing with a few more functions, it seems like there may be something wrong with the way the compiler handles the static keyword, in particular when declaring a static variable and assigning a function to it

function someOuterFunction(argument0)
{
  static someInnerFunction = function(argument0)
  {
    return argument0;
  };
  return argument0;
}

Confirming that the compiler is missing implementation for the static keyword
