Is there a std.zip.ZipArchive isDir or isFile method?

[mark]

I'm using std.zip.ZipArchive to read zip files, e.g.:

     auto zip = new ZipArchive(read(filename));
     // ...
     foreach (name, member; zip.directory) {
	if (name.endsWith('/')) // skip dirs
	    continue;
	mkdirRecurse(dirName(name));
	zip.expand(member);
	write(name, member.expandedData());
     }

As you can see, I am detecting directories with a crude test.

I really wish there was a method for this: and if there is, could 
you give me the link 'cos I can't see one in the docs?

(BTW The code above is slightly simplified: the real code won't 
unzip if there's an absolute path or .. present and also ensures 
that all members are unzipped into a subdir even if the zip has 
top-level names.)
