Traits (the Schaerli concept) are largely a solution in search of a  
problem in world of dynamic languages, IMHO, especially in Ruby since we  
have modules and mixins. To nip the potential  
method-redefinition-from-multiple-modules problem in the bud I  
collaborated with Mauricio F. and wrote the ‘use’ package that  
let’s you selectively include, exclude or alias module methods at the  
moment of inclusion.
