Can you elaborate on that point? I feel that Python's lambda is exactly
the same as the one in Lisp. Sure, the Lisp lambda supports multiple
sequential expressions (the "progn" feature), but I understand that
this is just "an extension" (although one that has been around several

Of course, Python's expressions are much more limited as Lisp's (where
you really can have macros and special forms in as the "expression"
in a lambda), but the lambda construct itself seems to be the very
same one.
