> A string literal, interpolation or block comment reaches the end of the file without being closed.

An error from the `lex` phase. `sakura explain V0002` prints this explanation offline.

A string literal, interpolation or block comment reaches the end of the file without being
closed.

Wrong:

```sakura
let s = "hello
```

Fixed:

```sakura
let s = "hello"
```

## Wrong program [#wrong-program]

[`compiler/tests/ui/V0002_unterminated_block_comment.sakura`](https://github.com/icantcodefyi/sakuralang/blob/master/compiler/tests/ui/V0002_unterminated_block_comment.sakura), which the compiler's ui suite runs through `sakura check`:

```sakura
fn one() -> Int { 1 }
/* this comment never closes
```

`sakura check --json` reports this record (pretty-printed; `$DIR` is the fixture's directory):

## Fixed program [#fixed-program]

[`compiler/tests/ui/V0002_unterminated_block_comment.fixed.sakura`](https://github.com/icantcodefyi/sakuralang/blob/master/compiler/tests/ui/V0002_unterminated_block_comment.fixed.sakura), which `sakura check` accepts with no diagnostics:

```sakura
fn one() -> Int { 1 }

/* this comment is closed */
```
