Yet another file,

  https://dataswamp.org/~incal/cl/bench/inclist-type-hints.cl

Here we have type hints, answering my own questions a while
back how to do it!

It is done with `declare', as in this

  (declare (optimize (speed 3) (safety 0)))

for the concerned function, then they are actually put to use
with `the'. ("Type hints enabled"?)

Elisp vs SBCL, in seconds:

  (faster 5.73 0.675997) ; CL is 748% faster

Note that the optimization worked a lot better for SBCL than
in did for Elisp, if we compare with the non-optimized (i.e.
no type hints) file I just posted [1] [it hasn't arrived
yet on this ML as I type this, but should arrive] - anyway

  (faster 5.86     5.73)     ;   2% - Elisp vs `cl-the' Elisp
  (faster 1.635993 0.675997) ; 142% - SBCL  vs `the' SBCL

SBCL become 142% faster with the optimization, and the Elisp -
just 2%.

Another interesting thing is that here, superficially or on
the interface level at least, we have the same type hint
possibilities as in SBCL.
