Pushing M-class into cleanupstack

Hi,

I noticed that when I push an M-Class object into a clean up stack, it will call a TAny* version of CleanupStack::PushL() and CleanupStack::PopL(), which just frees memory using User::Free().

Is there any way to insert M class objects into cleanup stack without creating my own TCleanupItem? Maybe some generic TCleanupItem designed for M classes?

Thanks,
