Strict and warnings: what comes first?
- use strict; use warnings;
- use warnings; use strict;
Please explain why below.
Update: Credits use strict; before/after use warnings; and Re^2: use strict; before/after use warnings;.
map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

- use 5.18.3; use warnings;
How many know that 5.12.0 was the first release that implies strict with use version? (well, actually 5.11.0, but I hope nobody is using 5.11.x in production code)
(I don't care what version notation is used)

As mentioned here, there might be some other options including -w and -W for warnings, and the implicit strict with use VERSION, but that would make a lot of possible answers if you were to enumerate all possible combinations...
And to answer the question, I put the more significant first, so version first (optional), because it is actually strict + features + minimal version, then strict (even after a version) because it is more restrictive (but less rewarningsive) than warnings, and at last warnings.
Edit: Oh, and if there's a package name, I always waste a few minutes deciding where I should put it, and then always add it after strict and warnings.

use strict;
use warnings;
is actually an attempt to
use less brain;
as it's a call for perl to do some of the thinking for you :) | [reply]

Some people try to keep their use ...; declarations alphabetically sorted, saying that might help merges when multiple people add different uses... If one was to follow that route, use strict; would come before use warnings;.

Ah yes, having so many use statements in a single file that you have to sort them to make them manageable, that happens all the time :'(. And having to add a bunch of modules in one go is common enough that two people do it in parallel on a daily basis. So annoying :/

Did you ever write a program in Go?

"Hello world!" counts.
But please note: This question might be hard to bear because it looks like Go isn't a TMTOWTDI language.
Yes []
