That won't make it for functions recursively building lazy sequences.
Anyways in common lisp :
CL-USER 1 > (defvar *bleh* 10)
*BLEH*
CL-USER 2 > (let ((*bleh* 100))
(lambda () *bleh*))
#<anonymous interpreted function 200D3762>
CL-USER 3 > (funcall *)
10
So I guess it's the cost of lazyness ! I'll just pass the indent
parameter around. It will be a problem to always do without specials
though.
Thanks
