File has a name property. You can do something like

auto file = File.tmpfile();
auto filename = file.name;
auto str = readText(filename);

I do grant you though that it's a bit odd to need to get the file name and 
operate on that rather than operating on the File object. It works though, and 
is a lot cleaner than reading in the file line-by-line, if you don't actually 
need to do that.
