Right now all integer numbers are treated as regular integers (avm 
doesn't support uint properly).
This means that 1 will be an integer and therefore foo(i:int) would be 
used. "1.0" becomes a number
so foo(n:Number) will be used.

Compile-time error, null is untyped, and there is no untyped method, 
:Object is of a type! Untyped would be :*!
To be clear one would need to write something like:;;

This could also apply to

If namespaces were supported in interfaces (which I don't know yet) the 
compiler could make[new QName("<reserved-character>String", "foo")]("");

or without namespaces:[str+"<reserved-character>String"]("");

For backwards compatibility that is certainly a good idea. Beware of the 
horror of using a swf compiled
with overloading support together with a swf that isn't.
