Re^4: Deleting duplicate lines from file

[Win]

The question is.

Why use

my (@lines, %line_md5);

when you can use

 my @lines; my %line_md5:

I don't really see that there is any point in grouping them together like that. I am thinking of putting a moto on my messages: Keep it simple when possible. Go complex when required.

Both are simple. Concentrate on your problem

[slightly edited and fixed a typo: Perl 5 doesn't make that much use of the colon!] The question is my (@lines, %line_md5); when you can use  my @lines; my %line_md5;

Because it's simpler, cleaner, easier to type and to read, and groups together correlated variables maybe?

I don't really see that there is any point in grouping them together like that. I am thinking of putting a moto on my messages: Keep it simple when possible. Go complex when required.

Indeed! Just be aware that the World's concept of "complex" is not bound to match Win's authoritative one...

PS: here's a motto: "don't put motos on your messages". Oh, or... was it all about Moto? This would explain a lot of things... but no: PM is definitely about Perl.

Sorry neither are simple. Simplest would be:

my @lines;
my %line_md5;

Here is clearly readable. There are no troubling lists to have to scan. Each one is on their own line. Simple and readble that is what people's code should be. Of course I wouldn't expect many on PM to understand that, given how much they love the Obfuscation section and how many ++ they give obfuscated code.

(and yes I'm posting as anon to avoid the -- that you morons will give this post).
