Yes, unpredictable performance is a price I'm willing to pay. I'm using a dynamic language after all.
If you aren't willing to pay it, just use typed variables. Or even native types, like num or int. Choose your own number representation -- there's more than one way to do it. The design philosophy in Perl 6 to make common things easy and other things possible; pathological number sequences are not the common case.
