For example, it handles deeply-nested objects, cycles/loops, and so forth. Unfortuantely, it seems some strange results for non-primitive types. For example: <pre lang="actionscript3"> trace(describeType(clone({bmd:new BitmapData(5, 5)}).bmd)) </pre> <pre lang="xml"> <type name="Object" isDynamic="true" isFinal="false" isStatic="false"> <method name="hasOwnProperty" declaredBy="Object" returnType="Boolean" uri="http://adobe.com/AS3/2006/builtin"> <parameter index="1" type="*" optional="true"/> </method> <method name="isPrototypeOf" declaredBy="Object" returnType="Boolean" uri="http://adobe.com/AS3/2006/builtin"> <parameter index="1" type="*" optional="true"/> </method> <method name="propertyIsEnumerable" declaredBy="Object" returnType="Boolean" uri="http://adobe.com/AS3/2006/builtin"> <parameter index="1" type="*" optional="true"/> </method> </type> </pre> So non-primitive types don't seem to come across like they do in my manual version. I guess both have their strengths and weaknesses. Thanks for the link! This is a good trick and solves some of the issues I pointed out in the article. For example, it handles deeply-nested objects, cycles/loops, and so forth. Unfortuantely, it seems some strange results for non-primitive types. For example:

trace(describeType(clone({bmd:new BitmapData(5, 5)}).bmd))
<type name="Object" isDynamic="true" isFinal="false" isStatic="false">
  <method name="hasOwnProperty" declaredBy="Object" returnType="Boolean" uri="http://adobe.com/AS3/2006/builtin">
    <parameter index="1" type="*" optional="true"/>
  </method>
  <method name="isPrototypeOf" declaredBy="Object" returnType="Boolean" uri="http://adobe.com/AS3/2006/builtin">
    <parameter index="1" type="*" optional="true"/>

  <method name="propertyIsEnumerable" declaredBy="Object" returnType="Boolean" uri="http://adobe.com/AS3/2006/builtin">
    <parameter index="1" type="*" optional="true"/>
  </method>
</type>

So non-primitive types don’t seem to come across like they do in my manual version. I guess both have their strengths and weaknesses. Thanks for the link!

I really like your <tt>clone</tt> approach and will be checking it out some more; very novel! I cleaned up some of the HTML formatting the commenting did so your quotes and whatnot should be restored. Thanks again! Wow, thanks for the contribution!
