Ok, let's make it more interesting...
The compiler is only supposed to error out on stuff that is actually
illegal according to the language.
What you are doing is not *illegal*, it just produces un-specified
behavior. ...
The behaviour is specified modulo evaluation order. An implementation
will just pick some evaluation order, it is not allowed to produce
arbitrary behaviour. In any case, it is a given that strict
left-to-right evaluation order will eventually be required, so I don't
think that it makes a lot of sense to discuss whether or not to error out.
