Keep in mind proposal #3 allows you to write code exactly as you would
in C++. You always use the semicolon as a statement terminator. It's
just that if you want to use a block as an expression (which is
forbidden in ordinary C++), you can leave off the final semicolon. So
it's really an extension to C++'s syntax, not a different sort of
behavior entirely.
Yeah. Only option 2 is "separators", and so far nobody likes that. Which
is good! I don't like it either. Let's assume it's dead.
Option 3 is the most-forgiving, in the sense that it disturbs the fewest
existing uses: expression-y lisp and ML people can write how they like,
statement-y C and C++ people can write how they like. The only users who
will be surprised are those expecting gnu-C-extensions; they will have
to leave a semicolon off to get the semantics they want.
And *all* proposals are compatible with adding a ternary operator (as a
shorthand). That's an orthogonal question.
