And I have taken short expressions with only a couple of operators, and 
given them their own method call, arguably taking more code (or at least 
line width) than the expression itself.  I did it because the little 
buggers confused me, and giving them their own named method made the 
code easier to follow, not because it made the code shorter.  But in the 
end I felt the change to a method call was totally correct.

It's a fine line, and judgement and experience are important.  Not to 
mention flexibility;  Wanja's example of a shop that refused to modify 
its coding policy until it was obviously counterproductive (and far too 
late to matter) is a great example of institutional inflexibility.
