Or the worst, considering that you then confusingly have two names for 
the same concept.

Trying to encode semantic differences (like between sal_utf16be and 
sal_utf16le) requires discipline (as it does not get any aid from the 
compiler's type checking), and when it starts to go sour it's probably 
worse than not trying to make the distinction in the type system in the 
first place (as now variables labelled to be of type sal_utf16be will 
misleadingly contain values of type sal_utf16le).
