It's legal, and benign, to prefix identifiers with '$'.
I use it in my code to identify the scope of a variable -- either _global
or class-specific (private). I find it useful to hang a '$_' prefix on
variables within a certain scope, not only to distinguish them a little,
but to make it easier to do certain things that utilize them, like create
accessor methods without having to invent a completely new name.
example:
private var $_someVariable:String;
public function get someVariable():String {
return $_someVariable;
}
public function set someVariable(value:String):Void{
$_someVariable = value;
}
