I'm not really sure if something like this is very useful, but it does hide the guts of implementation away from a designer.

Basically it's a class abstracting describeType a little bit more so a designer doesn't need to look at the E4X stuff and get spooked by it. They don't even have to know about describeType at all.

package

{

import flash.utils.describeType;

public class TypeDescriptor

{

public function TypeDescriptor()

{

}

public function getTypeName( value:* ):String

{

var varList:XML = describeType( value );

var result:String = varList.@name.toXMLString();

return( result );

}

And the usage is pretty simple:

import TypeDescriptor;

var foo:TypeDescriptor = new TypeDescriptor();

trace( foo.getTypeName( ["hello", "sup"] )); //Array

trace( foo.getTypeName( 5 ) ); //int

trace( foo.getTypeName( "hello" ) ); //String

trace( foo.getTypeName( new MovieClip() ) ); //flash.display::MovieClip

trace( foo.getTypeName( JessicaAlba ) ); //JessicaAlba (class from IDE & instantiated in the class itself)

trace( foo.getTypeName( this ) ); //if in a class (Application), something like com.ericd.projectOne::Application

Again, not very useful for developers perhaps, but it makes life easier on a designer. And I suppose you could add methods to retrieve different parts of the XML (base, isDynamic, isFinal, isStatic, etc.)
