The point is that the list of cases you have above is correct
*because* it does not include "when compiling". The compiler does not
evaluate the forms it processes, with a very few exceptions. AFAIK
the only forms in the compiled text that cause evaluation at compile
time are `eval-when' and friends.

`progn' does not evaluate anything at compile time.
