* `item ~ n` - Exactly *n* instances of item
* `item ~ n..m` - Between *n* to *m* instances of item (not recommended for wide ranges, due to performance issues)

Despite `~ n` being written with spaces, its binding power is the same as that of other operators,
for instance `a b ~ 3` parses as `a (b ~ 4)`, and `a ~ 2 b ~ 3` is parsed as `(a ~ 2) (b ~ 3)`.

**Examples:**
```perl
hello_world: "hello" "world"
