known issues and future improvements.

• Make JSXS be compatible with JavaScript 1.7 and E4X
  Introduce let and yield statements.
  enhancement; priority 1/5.
• Concat variable declaration in same function (if final is more short)

  var a = 'a'; a += 'a'; var b = a; 

  to :

  var a = 'a',b; a += 'a'; b = a; 

  feature; priority 4/5.
• Detect redundant value assigned by reference for add variable who factorize that

  var h = document.location.host,
  q = document.location.search,
  i = document.getElementById('myid');

  to :

  var a = document,
  b = a.location,
  h = b.host,
  q = b.search,
  i = a.getElementById('myid');

  feature; priority 4/5.
• Remove bloc statement ({...}) but leave semicolon in if .. else and some others statements

  if (condition) { statement1; } else { statement2; }

  to :

  if (condition) statement1; else statement2; 

  feature; priority 3/5.
• Parse "with" statement

  with (object) { object.attribute... ... }

  Actualy all the codes that it reports probably a syntax error.
  feature; priority 2/5.
• Reduce varname in "catch" statement

  try { ... } catch (myvar) { myvar... }

  to :

  try { ... } catch (a) { a... }

  enhancement; priority 1/5.
• Fix option "compatibility"
  This doesn't work if shrink option is desactivated.
  bug; priority 3/5.
• Convert object property string defined

  var a = { 'test': 69, "69": 'test' };

  to :

  var a = { test: 69, 69: 'test' };

  feature; priority 3/5.
• Reduce condition if true value

  var a = 'something'; if (a == true) { ... }

  to :

  var a='something';if(a){...}

  and

  if (true) { ... }

  to :

  if (1) {...}

  feature; priority 3/5.
• Advanced reduce logical condition according to operator precedence and priority

  while ( (a = (b || true)) || (b != (a > 3) && b < 4)) { ... }

  to :

  while ( (a = b || true) || b != a > 3 && b < 4) { ... }

  feature; priority 2/5.
• Detect redundant string value and assign to variable (if final is more short)

  if(a = "a value string" && b = "a value string"){}

  to :

  var c = "a value string";
  if(a = c && b = c){}

  feature; priority 3/5.
• Remove semicolumn between do-while when compatibility option is actived
