(Almost) everything is expression

[Mark S. Miller]

Insist on enclosing parens, since
  "(" introductory-token
is not otherwise legal


> let a = (switch (foo) {
>  case 10: 100;
>  default: 200;
> });
>
> 2. If-expression:
>
> let a = (if (foo) {
>  print('a is foo');
>  foo;
> } else {
>  // do some longer stuff
> });
>
>
> 3. Try-expressions:
>
> let a = (try {
>  // do dangerous stuff
>  "ok  value";
> } catch (e) {
>  "default value";
> });
>
>
> let a = ({
>  print('doing stuff');
>  100;
> });
>

Even the last is now easily unambiguous.
