My preferred solution would be to reject the 2nd alias 
declaration outright.

I don't see any value in intentionally creating the above 
pattern, _if_ it occurs then it's most likely due to an 
unintentional side-effect of a re-factoring, thus it should error 
out as close as possible to the real error.
