Avoiding <fx:declarations> tags in mxml classes to boost performance?
===

According to "The bAS3 Class", all declarations in a mxml class that are within a ´<fx:Declarations>` tag are in fact bindable.[ \[source\]][1].

So now I'm wondering what that does to the application's performance. To boost maintainability in my code, I've made quite a lot declarations like that, but since I'm developing a mobile app, I'm after the maximum performance I can get. 

Is it advisable to ditch the ´<fx:Declarations>` stuff altogether in favor of performance? I know that binding is quite heavy in flex, which is why I avoided it wherever possible.
