# Did you know, you can use the method `.none` (and friends) of `Any` in a method call chain?

    my \fib = 1, 1, * + * … ∞;
    say so fib[^10].none.is-prime;
    say so fib[^10].any.is-prime;
    say so fib[5..9].one.is-prime;

# A `Junction` is a parallel value that whats to collaps into a single `Bool`. Any method call to a definite `Junction` will be forwarded to its members, coerced to `Bool` and collapsed with the `Junction`-type. The above `any`-form is equivalent to:

    say fib[^10].map(*.is-prime).reduce(&[||])

# [`Junctions` https://docs.raku.org/type/Junction] come in many forms and can make you code quite neat.
