Crystal's <code>$w</code> literals create a whitespace-delimited array of strings at compile time
<lang ruby>require "time"
last_revision = Time.utc year: 2021, month: 2, day: 25
# the `%w()` literal creates an array from a whitespace-delimited string literal
# it's equivalent to %(string literal).split

The <code>qw</code> vocabulary provides Perl-ish syntax for arrays of strings. For instance, the literal <pre>qw{ a bc d }</pre> expands to <pre>{ "a" "bc" "d" }</pre> during parse time. This is convenient to use when the strings that are stored contain no whitespace.
