Re: [SMARTY-DEV] RE: [SMARTY] php5 Iterators.

Hello David,

What about using instanceof operator?
It would raise parser error on php4, but my thought is all php5 code
could be (temporarily?) moved into separate plugin that will be
conditionally included if Smarty is being run on php5 box.
Or maybe use runtime functions to avoid parser error.

I'm wondering, if is_a() is forward-compatible with interfaces?
