Perl 6

On debian: `apt-get install rakudo`.

Perl 6 does not appear to be available in the FreeBSD 10.2 ports collection.

The downloads page describes building from source (https://perl6.org/downloads/)

Try 'hello.p6':

    #!/usr/bin/env perl6
    use v6;
    say "Hello, Perl 6";
    "Hello, Perl 6, object-oriented style".say
    # A single line comment
    #`{{
    A multi-
    line comment.
    }}

Unlike Perl 5, method calls use a dot instead of ->, like:
    $foo.color

Unlike Perl 5, sigils are now invariable. This is huge.
    @array = [0, 3, 7];
    @array[2];    # 7

Reading a file into an array:
    my @lines = "file.txt".IO.lines;

Strict mode and warnings are on by default in Perl 6.

Since strict is in effect, variables are declared with 'my' for lexical local scope:
    my $x = 'foo';
    say "My x is $x.";

('say' is like 'print', but appends a platform-appropriate newline.)

To get user input, use 'prompt', which does 'say', reads STDIN, and chomps:
    my $answer = prompt "What the answer, fool? ";

Parens in Perl 6 are only for group, so a simple 'if' doesn't need them:
    if $answer == 'daffodil' { say "Yes!"; }

We have multi-line comments. Any kind of bracket works following the #`.
    #`(
        A
        long
        comment.
    )

Basic variable types:
    my $scalar = 'Foo';
    say $scalar;
    my @list = ('a', 'b', 'c');
    say @list[1];
    say @list[@list.end];
    my %hash = ('red' => 'apple', 'yellow' => 'banana');
    say %hash{'yellow'};
    my @colors = %hash.keys;
    my @fruits = %hash.values;
