I have an array of compiled regexes. What's the Best WayTM to compile one regex that's a disjunction of them all, that is, it matches if any of them match?

I know how to do all these: 

# 1.
my $any   = qr/one|two|three/;

# 2.
my $one   = qr/one/;
my $two   = qr/two/;
my $three = qr/three/;
my $any   = qr/$one|$two|$three/;

# 3.
my @pats  = qr/one/, qr/two/, qr/three/;
my $any   = qr/$pat[0]|$pat[1]|$pat[2]/; # ick

But I want: 

my @pats  = map qr/$_/, @some_input;
my $any   = ??? # no resort to explicit indices

Also, in my code the separate patterns are compiled much before the disjunction, so this is not what I'm looking for: 

my $joined = join ")|(?:", @some_input;
my $any    = qr/(?:$joined)/;
