Subject: File checks....

Is there anything in Ruby similar to Perl's if -r, -x, etc. switches? 
These switches work with variables as if they were files and they are
used in simple, silent and quick constructs like:
      if -r $file {
             print "$file is readable\n";
      }

Or am I forced to write all the code of File.new() and handle the
rescue exceptions myself?
