loading library

[eluser]aidehua[/eluser]
Thanks mddd - I was going to ask that very question: what are the consequences (none? slight performance hit? serious performance hit?) of loading a model, library or helper more than once?

E.g. auto-loading it but then loading it again in the controller, or loading a helper in a controller and also in a library loaded by that same controller.

(Obviously in a perfect world you wouldn't load things twice. But my application isn't a perfect world. Not yet, anyway.)

From what you say, this isn't something I should worry about, right?
