[toronto-lisp] Fwd: Development helpers

[Aleksandar Matijaca]

Hi there,

first of all Paul and Dave, thanks for replying!!  The question can perhaps
be best explained
with an example:

repl=> (defun doit-3 (x)
(* 3 x))
repl=> '(some more cool stuff)
repl=>'(and more and more)

i keep testing and playing around with functions
more and more

I can certainly run my doit-3 function

repl=>(doit-3 4)
12
repl=>

and now, I say to myself, - how the heck did I write that doit-3, I forgot,
because,
I wrote it 20 minutes ago, it obviously exists inside REPL because I can
execute it...
So, how do I view [dump??] the contents of doit-3 to the screen, or to a
file on the
disk, so I can invoke an editor and modify doit-3 and then reload it??

I am just interested in learning how to be more productive in a standard
software
development cycle.

Thanks, Alex.
