Hi!
You write:
Also, this can lead to more subtle BC breaks. Consider this code:
And then further on:
No backward incompatible changes, sin...
that can not be both right.
Ah, but the former describes the option that has been *rejected*. The option that was chosen instead does not have the BC break.
Personally, I would much prefer the backwards compatibility break to happen. It is frankly quite bizarre, and not at all useful, that the following two pieces of code behave differently: class Foo {} new Foo( print('hello') ); // silent vs class Foo { function __construct() {} } new Foo( print('hello') ); // says "hello" (Incidentally, HHVM doesn't have this "optimisation", and says "hello" in both cases: http://3v4l.org/ZDXs1) If I came upon this without knowing more, I would assume it was a bug in PHP, and any code relying on it was in need of fixing ASAP.
