No. &VALUE. (How often do I make mistakes? ;)

Constants in Perl are usually defined as subroutines. Often Perl can inline
them so there's no performance penalty.

The usage is:

    use YAML qw(VALUE);
    foo(VALUE);
    $foo->{&VALUE};

The '&' is needed on the last line because Perl would otherwise assume it was
the string 'VALUE'.

I'll teach you guys Perl yet! ;-)
