Here's my 2 cents worth: 
use strict;

my @foo1 = qw(1 1 1 1 1 1 1 1 1 1);
my @foo2 = qw(1 1 1 1 1 1 3 1 1 1);

print "Checking  \@foo1: ";
&ident_array(\@foo1);
print "Checking  \@foo2: ";
&ident_array(\@foo2);


sub ident_array($) {

    my $array_ref = shift;
    my $flag = 1;

    for(my $i=1; $i < $#{$array_ref}; $i++) {
        $flag = 0, last if $array_ref->[0] ne $array_ref->[$i];
    }

    print "array elements are ";
    print "not " unless $flag;
    print "identicle\n";
}

Wow, looks like davorg has got one heck of an elegant solution.
