Well, I don't want to provide every method of IO/File as a class
method like readlines/mtime. It's too clumsy. I'd like to provide
useful ones. I felt that the method to open file and read a leading
fixed sized content from it, then close the file, is not quite useful.
But IO#read provides the feature to read whole content too. Now, I
feel the class method to read whole content may be useful. Although,
File::open(s).read
will do the job (unclosed file will be closed by GC).
