Common Lisp over here like:

  * (+ (+ 1 1) (expt 2 256))

  * (+ 1 (+ 1 (expt 2 256)))
  115792089237316195423570985008687907853269984665640564039457584007913129639938

Python will happily do this too, if you remove the ".0" in the example, the values become integers, instead of floats, and the computation is precise.

The point is to demonstrate a property of IEEE floats, not the language. I'd expect CL has some means of using IEEE floats too, and with the appropriate syntax, the same issues could be demonstrated.

Many languages support BigFloats and BigInts, but this discussion is about IEEE 754 floats vs Gustavson's proposals.
