Comment on Understand why you probably don’t need prototypes by Raymundo

Thank you for your easy and kind articles, always.

I have a question about this article. What does the prototype of “each_array” mean, in List::MoreUtils? (same about “mesh”)

At first, I though that each_array could receive only up to 25(1+24optional) arguments, that is, array variables. However I tested it a moment ago and it worked well with 30 arguments.

That’s already in Item 49. Create closures to lock in data.

Use of ‘state’ instead of ‘my’ or ‘local’

Hi, brian!

Thanks for the great tips on Perl. Here is what I’d like to see tackled.

1. Identification of pre-UTF8 encodings (ISO, Windows, Mac, etc.) and conversion into UTF-8.

2. Recovering UTF-8 encoded text that has been corrupted, e.g. the Greek word δοκιμή appears as Î´Î¿ÎºÎ¹Î¼Î® or, even worse, Ã?Â´Ã?Â¿Ã?ÂºÃ?Â¹Ã?Â¼Ã?Â®.

3. Constructing regular expressions to match mixed Right-to-Left and Left-to-Right text.

4. Turning a perl script into a distributable binary without the Perl Dev Kit.

Thanks again for your excellent work!

Comment on Use branch reset grouping to number captures in alternations by brian d foy

The problem is your second alternation and precedence. If you group (?:(Barney)|(Fred)) so that | only applies to them, you get the output you expected.
