Could we alias File.empty? to File.zero? ?

The latter already exists. I tried to use File.empty?
and then thought it would not exist, but the code
already exists, it is just called File.zero? instead.

I added a comment on issue #10121 before knowing this specific issue already existed.

I just wanted to say that, with the arrival of Dir.empty?, I like the idea of the File.empty? alias for the reason of having some symmetry between Dir and File methods.

OK, agreed.

[backus (John Backus)]

For the sake of consistency could you also add Pathname#empty?. Alternatively maybe add both Pathname#empty_file? and Pathname#empty_directory?. It is probably important to keep Pathname consistent with File and/or Dir since the tool is much less useful if you sometimes have to fallback to File or Dir for certain use cases

John, this feature is already closed. If you want your proposal to be
looked at, please open a new one, referencing this one.

Thanks, Martin.
