Please never even considering semicolons to be optional in D. I once hit a optional semicolon issue in JavaScript, that took two weeks to debug. I hate that feature since then (~2005).

If you don't want to use semicolons, just use Python-like syntax, and then run it thour some converter for example.

function foo()
{
    return
    {
        foo: "bar"
    }
}

console.log(foo())

What does this log? "undefined", obviously, what did you expect?

I learned this the hard way too.

Will not work unless it is `void foo()` function.
LDC will also complain about unreachable code, at least in release/optimization mode.
It is also another story in languages with implicit last statement return like Nim or Kotlin (and Rust IIRC).

Yeah.

How about this:

```javascript
function bar(x) { return x; }
function baz(x) { return x; }

function foo(aaaaaaaaaaaaaaaaaaaaaaaaaaaa) {
  return bar(aaaaaaaaaaaaaaaaaaaaaaaaaaaa)
         + baz(aaaaaaaaaaaaaaaaaaaaaaaaaaaa);
}
console.log(foo(21))
```

Learned very hard way.

Since when? I use LDC 1.24 and it won't compile without semicolons...
