BTW, taking more hints from Math::BigInt, you would probably end up making your intervals objects, and you would be implementing an add() method. Then you'd use operator overloading to achieve a pleasant syntax. So yes, I do see code like $arg1->add($arg2), except you'd hide it behind an overloaded + operator: 
use overload (  '+' => \&add );
# now $arg1 + $arg2 will be handled as $arg1->add($arg2) behind the sc
+enes.

Just thought I'd mention that.
