Greg Dove commented on FLEX-35283:
----------------------------------
I assume GCC made the 2nd parameter 'required' to avoid slower performance in
situations where the radix ought to be known, or could easily be known by the
developer. So it's almost like a 'behavioural optimization' of the js
developer, because they must make a conscious decision :).
In our case we continue to let actionscript developers take the easy route,
which might mean code that runs slower in cases where the developer could
easily add the radix when they did not (because they know what it should be)
and have it run faster.
