I've been following this discussion with keen interest. Although my
Liitin.org project is far from minimal in size (viable sized by design),
it does have some common objectives. Racket is used as "the native

Not to give an excuse to design the argument order poorly... it would be great

I'm currently experimenting with Tony's racket/stomp package that you might

practise.

Hi,

code by code so that the outcome is the modified source code with the
original formatting and comments. For example...
BEFORE:
";; comment1
(list 'a ;comment2

)"
>> (a b)

Then the helpers could do all the work needed.
