const questions

//#1
// Current spec would suggest that this is an early error during compilation of the main code.  
// However, dynamically, the "x=20" will write to the "var x" declared inside g.  
// This is a case where the early error for assignments to const variables appears to overreach, flagging an error which will not actually occur if the code were allowed to run.
function f() {
  const x = 5;
  function g() {
    eval(“var x = 10”);
    x = 20;
  }
}



//#3
// It was suggested on es-discuss that this should be an early error during the 'eval'.
    (function() {
        eval("const x = 4");
        const x = 3;
    })();
