bool foo {
in(bar) { ... }
out { return ... }
}

Actually it's also enough with the surrounding scope.
And fast to write, just one line:
bool foo in(bar) {...} out {...}
Everyone that sees this for the first time can see what it means. And
it's more intuitive syntax than
bool empty { ... }
void empty=(bool b) { ... }
With the first syntax above you would have to specify the type (bool in
this case) only once.
