That's why, if we're going to elide the last semicolon in the block, doing that should not change the meaning of the last statement. -- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.

Well,= there is also no way to tell, whether "return dosomething2()" is= void.
Look here for an=C2=A0Example.
Does this even answer the c= oncerns that you had?

My point is that it = isn't clear whether the user wanted "return dosomething2()`= or whether they just wanted to call `dosomething2()`. That's wh= y, if we're going to elide the last semicolon in the block, doing that = should not change the meaning of the last statement.
