OK, that explains. In ruby 1.8.7 it works as documented in the
Pick Axe book (only class method on File, no instance method).

Thanks for clearing that out :-)

<code>
peterv@ASUS:~$ rvm use 1.8.7-p334
Using /home/peterv/.rvm/gems/ruby-1.8.7-p334

peterv@ASUS:~$ ruby -v
ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-linux]

peterv@ASUS:~$ irb
001:0> f1 = File.open('test','w')
=> #<File:test>
002:0> f1.size
