// Note: there are bugs in hygienic renaming, so this doesn't work all the time yet.

macro varr {
  case [$var (,) ...] = $expr => { 
      var i = 0;
      var arr = $expr;
      $(var $var = arr[i++];) ...
  }

  case {$var (,) ...} = $expr => { 
      var obj = $expr;
      $(var $var = obj.$var;) ...
  }

  case $var:ident = $expr => {
      var $var = $expr
  }
}

varr [x, y, z] = [0, 1, 2];
console.log(x, y, z); // 0 1 2

varr {x, y, z} = {x: 5, y: 6, z: 7};
console.log(x, y, z); // 5 6 7

varr w = 10;
console.log(w); // 10
