since only false and nil are failed predicates in ruby i find it quite uesful
for boolean methods to return a value

   if((sql = conn.commited?))
     log sql
   end

etc.  i avoided '== true' test to explicitly allow this behaviour.  it's
certainly fine to only return true, however.  it's a religious choice in the
end.
