Variable is assigned but never read not triggered when variable only assigns itself

Environment: SonarLint for Eclipse 3.6.1008

def var foo as int.

foo = foo - 1.

Nothing is actually using foo, so the 'variable is assigned but never read' rule should be flagging it, ie an assignment of a variable to itself should not count as "reading" it.

Right, the engine currently doesn't take into account this case.
