Of course it's possible to read in the open file into a string. It's just that the only function in Phobos for doing that is in std.file and does not operate on a File. All of the File functions read in only a portion of the file. So, either a new function would have to be added to File, or you'd have to write one yourself (which wouldn't be all that hard using what's already there). - Jonathan M Davis
