Subject: Re: [Jprogramming] Code smells in J
How to de-smell this:
3([* i.@#@,@[ ^/ i.@>:@])~ 0 0 1 1 1
?
I tried but in vain.
Thank you!

Thanks! Bo.

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,
