SimpleVar node is a plain PHP variable where it's name is a simple identifier.

For example, $x is a simple var. $$x is not a simple var, but rather a Variable, where VarName is a SimpleVar.

type Var

type Var struct {
	FreeFloating freefloating.Collection
	Position     *position.Position
	Expr         Node
}

Var is an expression that evaluates to a variable. Unlike SimpleVar, it can contain complex expressions.

Here are some examples:

$x     - SimpleVar.Name="x"
$$x    - Var.Expr.(*SimpleVar).Name="x"
${"x"} - Var.Expr.(*scalar.String).Value="x"
