> This issue is mainly about memory optimization
> It comes from profiling a real world (complex) application on mobile & desktop
> Optimizations will also apply to desktop
> mx.binding.Binding use exception/error as control flow.
> While it's perfectly valid, it's seems to be very bad from the memory allocation side (as reported by Scout)
> Will provide a patch as a basis for discussion.
