Yep, that's right... but it's not easy to know if that distinction is needed
for every single variable (why it's easier to work around this issue at the
sinks, as Rector now does).
I assume the next step is for PHP is to deprecate null coercion for all
contests; e.g. concat ('Search: ' . $search), comparisons ('' != null),
arithmetic, and the remaining functions like print()/echo()/sprintf('%s')...
and then deprecate all other forms of coercion (e.g. 5 + '3')... because that
will be fun :-)
