I have no problem with the name, only with the interface...

Sorry...I don't understand. Either that or I haven't properly explained what the comparator does.

The comparator method doesn't do any work other than to set a value to be compared with the compare method. So these two are exactly equivalent: 

my $difference = $embedding->compare($embed2, $embed1);

$embedding->comparator($embed1);
my $difference = $embedding->compare($embed2);

The only time it makes any sense to use the comparator method is when there are lots of values to compare to the same thing: 
$embedding->comparator($embed1);
my $diff2 = $embedding->compare($embed2);   # Compares $embed2 to $emb
+ed1
my $diff3 = $embedding->compare($embed3);   # Compares $embed3 to $emb
+ed1
my $diff4 = $embedding->compare($embed4);   # Compares $embed4 to $emb
+ed1
my $diff5 = $embedding->compare($embed5);   # Compares $embed5 to $emb
+ed1
my $diff6 = $embedding->compare($embed6);   # Compares $embed6 to $emb
+ed1
my $diff7 = $embedding->compare($embed7);   # Compares $embed7 to $emb
+ed1
# ... etc ...
