-`&` refers to the value passed to the block. You can read more about it [here](https://crystal-lang.org/reference/latest/syntax_and_semantics/blocks_and_procs.html#short-one-parameter-syntax).

 **the long answer is: Yes! But ...**
 the method [Enumerable#any?](https://github.com/crystal-lang/crystal/blob/932f193ae/src/enumerable.cr#L81) is not implemented using `Enumerable#reduce` but with `each` so to "break the loop" once we find an element that satisfies the condition.
