ok. it works on your example. but if i defun your anonymous function, the
result is not as nice :
* (defun f2 (a) (princ a) (incf a) (princ a) a)
F2
* (step (f2 17))
; Compiling LAMBDA NIL:
; Compiling Top-Level Form:
Stepping the form
(F2 17)
using the debugger. Type HELP for help.
*Step*
("LAMBDA NIL")
Source: #'(LAMBDA () (F2 17))
6] step
1718
18
*
the compilation is "too" good ;-)
perhaps keeping source for interpreted evaluation could be a solution ...
ctu.
