Nope. The match function populates a list of special variables in the
form $1, $2, $3. Generally, we access them within a conditional which
ensures that we captured the right number of matches
if (($string =~ /my_reg/g) == 3) {
my $this_n = $1;
my $that_n = $2;
my t_uthrun = $3;
They can also feed a list as an lvalue, though, without ever explicitly
addressing the numeral variable [I just checked it out ;-o)
Greetings! E:\d_drive\perlStuff\giffy>perl -w
my $string = 'bare baby baboons';
my ($first, $second, $third) = ($string =~ /\bba(.*?)\b/g);
print "$first\n$second\n$third\n";
