For a while I used to use a Perl-inspired `q("red green blue")` as a shortcut. That's one character more than the proposed syntax, I leave the one line implementation to readers.[*]
Despite saving some characters, it wasn't important enough to bother keeping in a utility module, let alone song as single-purpose syntax.
[*] I did this long enough ago that the implementation probably involved `import string` ... Something only us folks quite long-in-tooth remember.
