Dylan still has a number of primitive operations with hard-to-predict
timing behaviors.  Method dispatch requires O(n log n) time for n
methods with simple argument types, and even greater time for (say)
type-unions of limited integer types.

So Dylan still requires moderately deep language knowledge, if you're
aiming for speed...
