delete and MmFile

[NewName]

Hello everybody.
So I heard that `delete' is being deprecated?

If that's true, what can I do to close an MmFile?
Or is there another way to create an MmFile object, other than with `new', so
that it gets destroyed when out of scope?

My problem is, I need to reopen the same file outside an if() block. If the
conditional is entered and I don't delete the MmFile in it, my program will
crash at runtime.
Presumably for trying to map the same file twice.

Thank you.
