Usage of flash.utils.describeType can be expensive, consider caching the results.

[GoogleCodeExporter]

When using flash.utils.describeType to describe a large class can be improved 
if the results are cached for later use. Borrowing from the Flex SDK, usage of 
DescribeTypeCache and DescribeTypeCacheRecord (minus the Flex SDK 
dependencies) can improved performance.

Update to DescribeTypeCache to 
getDefinitionByName("mx.binding::BindabilityInfo");

Hi, we have no need to cache the describeType result since it is only used once 
for each Type that is created. The Type instances themselves get cached, so for 
each call to Type.forInstance()/forName()/forClass() there's only one call to 
describeType().
