    No it's not dangerous. Your operator() is stateless - it does not matter
    which instance it is called on, as long as it's called once for each
    string in proper order. for_each guarantees the latter.

With sufficient thrust, pigs fly just fine. However, this is not 
necessarily a good idea. It is hard to be sure where they are going to 
land, and it could be dangerous sitting under them as they fly
