Permutations and Recursion
I've been working on an implementation to generate the result with arrays (rather than strings) but have been running into some issues. I'll try to post more about what I've come up with as soon as I find more time.
You're correct about the "arrays of arrays" part. This is one area of Perl that has been challenging for me. I just need to find time to read through all of the excellent documentation!

Perl Weekly Challenge 87: Longest Consecutive Sequences and Largest Rectangle
Yes, C.-Y. Fung, you're right. There was a small bug in the code, which no longer looked at the last column of the matrix. I don't know how this bug came in, as the code was originally correct, I guess I must have made a faulty copy and paste at some point. I've fixed it now. Thank you for bringing up the topic.

Perl Weekly Challenge 93: Max Points and Sum Path
Hi Ben, I basically agree with C.-Y. Fung's answer. My method definitely doesn't look for points like (0,0), (1,2), (2,4). As I said in the introduction part, it appears that the given co-ordinates will be integers, that the points of a straight line have to be immediate neighbors (i.e. no gaps between them) and that the lines can only be horizontal, vertical or diagonal. Points like (0,0), (1,2), (2,4) don't fit this bill.

Perl Weekly Challenge 93: Max Points and Sum Path
Checking for collinearity of three points in the completely general case is a matter of calculating the determinant of
1 x_1 y_1
1 x_2 y_2
1 x_3 y_3like this
Some other people such as Dave Jacoby had examples like this:

Some people on reddit also answered your query:
https://www.reddit.com/r/perl/comments/koahhf/from_a_reflection_on_the_weekly_challenge_092/
The replies might sound a bit sarcastic but that is because it's actually quite a well-known problem.
