Yes, I was half-aware of that, because of the

"...but the order of evaluation with respect to the evaluation of
top level forms in the file is implementation-dependent."

passage in L-T-V description, but I was not sure if it applies to
EVAL-WHEN.

I think this is one of the places where the CL spec could be improved,
by decreasing the astonishment factor :-)
