Local function parameters appear to be entered in wrong scope.

The error message below complains that the formal is a duplicate definition - is it being entered into the wrong scope?

bug7.dart:
main() {
  tag(tag, s) => s === null ? '' : '$tag$s';
  print('${tag('x=', 8)}');
}

$ frogsh --enable_type_checks bug7.dart
bug7.dart:2:7: error: duplicate name "tag"
  tag(tag, s) => s === null ? '' : '$tag$s';
      ^^^

The trick is, it can't be entered into the enclosing scope either, because of cases such as:
void main() {
  print((fib(x) => (x <= 1 ? x : fib(x-1)+fib(x-2)))(10)); // works: 55
// print(fib(10)); // error: fib not declared
}

suspect we need to do something goofy for lambda expressions, like generate an intermediate scope if they happen to have a name.
