Common Lisp has 'eval'. Apart from that, Dylan is more powerful (and a 
lot cleaner):

In Dylan, everything is an object, a direct instance of exactly one class.

Dylan has union types, limited types and singletons, all of which can be 
used as variable and constant types and specialising types in generic 
functions and methods.

Dylan has libraries for hiding implementations, and the ability to seal 
classes, generic functions and domains of generic functions to those 
libraries.

Dylan has no previous language legacy to support.
