Re: [SMARTY-DEV] feature request: isa operator

So you are making the presumption that objects == business logic? I don't think so. Objects are extremely useful but you have to be careful how you use them, this is no different than custom functions. Now this isa stuff... I don't see its practicality for the core. If you want it, build your own functions & prefilters. Monte On Wed, 2003-06-18 at 08:45, Andrei Zmievski wrote: > Stop. Putting. Business. Logic. In. The.
