If the item is null, it should indeed return 0.
Except since 7.2.0 it issues a warning as well!
Have to do
echo count((array)$item);
to shut it up ...
Isn't it just:  	 @count($item) 	 ???

We are told that '@' will be dropped at some point? But perhaps it IS the right solution to fix what simply looks like a mistake anyway.

What I AM trying to establish is just what is the 'correct' way to do these things since it is obvious that the methods used for 20+ years are no longer acceptable? @ may work as a fix today, but for PHP8?

Although I'm tempted to nail down PHP7.2 in much the same way I used PHP5.2 for over 10 years and by then I'm well into retirement and can leave it to someone else to do the next re-write :) So perhaps 'count(' -> '@count(' may be the correct solution. The feedback on the Smarty forums suggest simply rolling back to 7.1!
