otoh, discussing about Kansas (an ORM lib by Kirk Haines)
Kirk came up with a case where he would like to redefine
the !=  (and others)

Quoting Kirk from IRC:

13:37 < wyhaines> Kansas lets one construct queries of the database
using Ruby statements.  Basically,  method_missing plus overrides
intercepts the Ruby and makes sense of it.  So:
13:37 < wyhaines> ksdbh.select(:Foo) {|f| f.some_field == 'thingy'}
13:37 < wyhaines> works fine.  However, an inequality is a problem
because != can't be overridden.
13:38 < wyhaines> I can do:
13:38 < wyhaines> ksdbh.select(:Foo) {|f| f.some_field.not_equal 'thingy'}
13:38 < wyhaines> but that's ugly.  I haven't found any other option, though.


So there you go, in this scenario at least, the evil would be useful
and would make more readable code
