It would just break too much. I see lots of scripts that have things like
this:

$var = '12 beers';

echo $var + 4;

and they expect it to be 16 of course.

Or what about badly trimmed strings, when reading from a file it can
include extra line endings and it's so much easier to just ignore that
because PHP will convert it just fine.
