Extensions do make things a little more complicated, but again, there's almost no precedent here, and pretty much everyone agrees that this new scope-private access level shouldn't give access to extensions. That also means there's an option to keep yourself from accidentally accessing scope-private members in a member type: put the member type in an extension.</div></div></blockquote><div><br class=""></div>The only example that comes to mind is Ruby, where I can add new methods to an existing class, and those new methods indeed have access to existing ‘private’ methods:</div><div><br class=""></div><div>class A</div><div> private def foo()</div><div> puts “foo called”</div><div> end</div><div>end</div><div><br class=""></div><div>A.new.foo() # error</div><div><br class=""></div><div>class A</div><div> def bar() # add new bar method</div><div> foo()</div><div> end</div><div>end</div><div><br class=""></div><div>A.new.bar() # prints “foo called”</div><div><br class=""></div></body></html>
