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).
