A common usage of continue is to allow some loop-end code to execute even when next is used to provide an early exit from a loop iteration. Consider:

use warnings;
use strict;

for my $yodda (1 .. 4) {
    print "Odd is " and next if $yodda & 1;
    
    print "Even is ";
} continue {
    print "$yodda\n";
}

Prints:

Odd is 1
Even is 2
Odd is 3
Even is 4

Often early exits are used to avoid excessive control structure nesting - especially of if controlled blocks
