You really should go over the readme. My first view and I saw at least two typos. You used 'the the' at your text line 22

The 12 12 12... is missing a single quote at least I think that is what it is but is it? Are you using tick marks?
So that's about as far as I've gotten. Thanks.

I saw the RubyCon video on YouTube and so I looked you up here by name rather than the posted url.

Just for fun I was playing around with something in Ruby while I was watching the video.
I'm no expert but this gave me insight for "grade up".

[2,5,1,0,6].each_with_index.sort
=> [[0, 3], [1, 2], [2, 0], [5, 1], [6, 4]]

Then I got it to figure out what was going on with...

[2,5,1,0,6].each_with_index.sort.map { |e| e[1] }
=> [3, 2, 0, 1, 4]

Those Ruby guys might have been able to understand this better if you used examples like that.
Just a thought. I might have gotten bored though if I didn't try to figure this out on my own.

👍

I'm 62 now and never had a profession as a programmer but about 2007 started to learn some Ruby.
I'm passionate about it now. But alas I think my brain was damaged by BASIC.

Hey! This isn't an issue exactly, but I just thought I'd let you know that I independently had a similar idea, though I haven't got very far with the implementation yet: http://github.com/marnen/apl-gem. (I may try to use jop for inspiration now that I know it exists...)

I'm very excited about this project! J has so many interesting ideas for array manipulation (and they are all incredibly terse). Wouldn't it be awesome if this syntax worked seamlessly with fast numeric arrays?
