My point is about potential problems in backwards compatibility.<P>
A transformation of a string or a number into another string or number is common, BUT the transformation of refs is impossible.<P>
Hence it's far more likely that legacy code will break if something like <C>$_++</C> became illegal for an aliased input like <C>3+4</C> .<P>
Same code for refs wouldn't make sense at all.<P>
I can't come up with more intuitive examples, but I'm sure those exist.<P>
