Thank you, cameyo. I think the argument "lst" of "f" has been evaled during the call of (f a), so why must it be evaled again by "letex" in function body ?
And could you please give more information about the function "typeof"?

Hi lyl,
i'm not an expert, but i think "evaluated" is different from "expanded". Maybe a guru will highligth this question.
The typeof function show the type of the argument; the core function is dump (see the manual for information).
