Challenge 2: Named Captures for a Date — Possible Solution
====================================================================

use strict;
use warnings;
use feature 'say';

my $date = "2026-07-10";

if ($date =~ /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/) {
    say "Year: $+{year}, Month: $+{month}, Day: $+{day}";
}

Output:
Year: 2026, Month: 07, Day: 10

WHY THIS WORKS AS AN ANSWER
------------------------------
(?<year>\d{4}), (?<month>\d{2}), and (?<day>\d{2}) each reuse the
chapter's own named-capture syntax exactly — (?<name>...) — applied
to three separate groups instead of the chapter's own date/level/
message log-line example, with \d{4} and \d{2} reused directly from
Course 1's regex quantifier syntax to match exactly 4 and 2 digits
respectively.

$+{year}, $+{month}, and $+{day} reuse the chapter's own %+ hash
access pattern precisely — each named group's captured text becomes
retrievable by name through this special hash, immediately after a
successful match, with no need to track which numbered $1/$2/$3
position corresponds to which piece of the date.

Interpolating all three directly inside one double-quoted string,
"Year: $+{year}, Month: $+{month}, Day: $+{day}", reuses ordinary
string interpolation (Course 1, Chapter 2) — hash-element access
interpolates inside double quotes exactly like a plain scalar
variable does, producing the full formatted sentence the challenge
asks for in a single say call.
