The code smell which bothers me worst, in J, is the "not getting started"
smell.
When I am afraid of writing a rough draft because it would be ugly, I
don't get anywhere. And, once I have a working draft, I can use that
to test variations which would be more concise, more understandable,
which get past machine bottlenecks, which have clearer interfaces
and/or more straightforward documentation.
Anyways, not putting my heart into it is a smell.
Thanks,
