0.6.7

Improvements

• The reference operator is now covered by PhpCollective.WhiteSpace.ImplicitCastSpacing (#82). That sniff already owned this shape for !, @ and unary minus, so & $list joins it rather than arriving as a separate sniff.

  $bad = & $list;                             // reported
  foreach ($items as & $item) {}              // reported
  foreach ($items as $k => & $v) {}           // reported
  function f(array & $items) {}               // reported
  function g(& ...$args) {}                   // reported
  
  $ok = &$list;                               // untouched
  $okBitwise = $a & $b;                       // untouched
  function h(int $x = self::A & self::B) {}   // untouched

Telling a reference from a bitwise and takes more than the preceding token, since a type hint precedes the marker in function f(array & $items) and reads exactly like a left operand. A reference is one that stands in front of a variable, or the ellipsis of a by-reference variadic, and either follows something that cannot end a value or sits in a parameter list.
