No I don't think they should be banned.  Though I will admit that I would 
vote against they're use in every project I'm currently familiar with.  
But I think they should be considered on a case by case basis, and not 
banned with a blanket statement.  They provide a runtime behavior that 
could be desirable in some circumstances.
