If your having performance problems then submit a patch
allowing the implementation to call #{bean.booleanFunction}
only once for a given phase in the cycle, assuming this
behavior is still ok w/ the spec. I don't think it's going
to get very far however since the resources used to evaluate
an EL binding are insignificant compared to the real bottle
necks we face, like SOAP requests or table scans. BTW, it's
@rendered, not @render.
