Variable Functions (and Classes)

Question

Hi, I was wondering if ActionScript had some way to call functions and classes from variables, like they do in PHP:
function funcname() {
     print "Potatoes come from tree";
$function = "funcname";
print $function;   // Prints out "funcname"
$$function();      // Prints out "Potatoes come from tree"
In case you don't know the syntax for PHP, you should know that anything perpended with a $-symbol is a variable. Is something akin to this possible with ActionScript?

flash uses array notation to convert strings to objects:
function funcname() {
     trace("Potatoes come from tree");
var fS:String = "funcname";
this[fS]();
