In Java (C, C++ and others) braces are optional for statements like if,
while, for and so on, containing only one expression. In D this is true
as well, but compared with Java, D also allow try, catch and finally
statements to have optional braces.
What about extending this to allow optional braces everywhere, where the
braces contain a single expression? I'm thinking this will be most
useful for functions/methods, templates and delegates. Specially for
methods acting as properties that just forwards a value.
Examples:
class Foo
{
private int a_;
int a () return a_;
int a (int a) return a_ = a;
}
template Bar (T) alias T FooBar;
auto foo = delegate () return 3;
auto bar = return 3; // don't if this would be possible
One thing I'd subjectively like is to require braces on both branches of
if/else if at least one has braces.

Why is that?
