in reply to Re^8: Shouldn't references be readonly? (updated)
in thread Shouldn't LITERAL references be readonly? (updated)

My point is about potential problems in backwards compatibility.

A transformation of a string or a number into another string or number is common, BUT the transformation of refs is impossible.

Hence it's far more likely that legacy code will break if something like $_++ became illegal for an aliased input like 3+4 .

Same code for refs wouldn't make sense at all.

I can't come up with more intuitive examples, but I'm sure those exist.
