According to the announcement in the forums, FileHandle should be part of FoundationEssentials. But currently it isn't. I know the new Foundation might still be a bit incomplete, but since a file handle seems to an essential (sic!) part of Foundation, I am wondering if it might have been replaced by something else, and if yes, is there a kind of list for replacements like that or for parts that are still missing? Do I have to import the full Foundation for now the get FileHandle?
