The operative word was "silent". The actual behavior is fine, but the silence
is unexpected. For example, PHP happily accepts substr('foo', 'bar') with no
complaint at all. From a purely philosophical perspective I think almost
everyone would expect *at least* a strict notice.
On a practical level, we have a major barrier and we'll have to decide how to
handle it. As I see it we could do one of the following:
1. Discard consistency (!!)
2. Try to convince people to make these bizarre conversions not silent (BC
break)
3. Try to find a creative solution to be consistent without changing anything
about the conversion behavior. (I'm not seeing a way to do this one, unless we
redefine "consistent".)
