The first time you do a dir() of Form, we have to use Reflection to introspect - every member on Form - every member on ContainerControl - every member on ScrollableControl - every member on Control - every member on Component (aka the inheritance hierarchy of Form :D )
After that, the members are all cached and subsequent access should be quite fast.
