Escaping happens if you use interpolation into the string template:
```
let re = RegExp.re`(?x:
(\d{3}-)? # area code (optional)
${ /\d{3}/ }- # prefix
\d{4} # line number
( ${ "*" } \d+ )? # extension
)`;
```
If the interpolated expression is a regexp, then things seem
relatively straightforward (although there are corner cases to
consider). If the interpolated expression is a string, then it is
suggested that you use some sort of automatic escaping.
