Wait. I'm confused. {$foo->bar()->display()} would break backwards
compatibility, but rewriting Smarty for PHP5 wouldn't? Plus, how
would allowing for {$foo->bar()->display()} break Smarty's ability to
run on PHP4? It would only break that template's ability to run on PHP4.

I see a few solutions here:

1.) Just make it so Smarty can handle PHP5 dereferencing. This would,
of course, break the templates (again, not Smarty itself), if they
were ran under PHP4.

2.) Have two versions of Smarty (2.x is PHP4, 3.x is PHP5). I'm sure
this is probably already in progress to some degree (PHPUnit and
phpDocumentor both have dual versions out right now).

The fact still remains - Smarty is broken under certain circumstances
for PHP5. To get around this problem you will have to do the following:

{assign var="bar" value=$foo->getClass()}
{$bar->display()}
