 / @emkornfield:
   I've at least seen in the wild two columns containing the same name only 
diverging by case sensitivity.  I agree we should recommend against them since 
its not clear they will be able to handled well.  If we do update docs, we 
should also recommend against naming columns using "." as a delimeter as this 
can also lead to ambiguity.
