Re: Equality of strings

Didn't you get a warning from this code?

$ perl -Mstrict -wE 'my $str = "[]"; say $str == "[]" ? 1 : 0'
Argument "[]" isn't numeric in numeric eq (==) at -e line 1.
Argument "[]" isn't numeric in numeric eq (==) at -e line 1.

$ perl -Mstrict -wE 'my $str = "42"; say $str == "[]" ? 1 : 0'
Argument "[]" isn't numeric in numeric eq (==) at -e line 1.

You're not seriously still running your code without warnings enabled, are you? While simultaneously trying, based on your last few questions, to increase your test coverage numbers?!

The way forward always starts with a minimal test.

This is precisely the sort of "technically correct" yet unnecessarily abrasive comment that drives people away from communities. You're a smart person; surely you can find more constructive ways to offer feedback than getting all hot and bothered because someone is making a few mistakes along road of learning a new skill (not to mention giving this community a continuing reason to exist!) I'm asking you, gently, and as a fellow member of this community, to please do better.	[reply]

You should do a little research before scolding. I and many other monks have been providing several hundred answers to this Seeker's 100+ posts for about a year and a half. S/he's been the beneficiary of scores if not hundreds of hours of mentoring by some of the most skilled and experienced, and generous, Perl programmers there are. We've provided many dozens of example scripts and snippets, all showing `use strict; use warnings;`, and many recommendations to read and reread the fundamental Perl documentation. ovedpo15 suffering from using `==` in place of `eq` for string comparison and not employing Perl's protection-from-silly-mistakes features including the `warnings` pragma, after all this time, is obstinate and willful programmer negligence, disrespectful of those who take time to assist, and deserving of clarion criticism. You're not doing this monk any favours by shielding him/her from criticism from the peer group s/he has chosen to join, when s/he insists on not following the most basic advice, even while asking a new and more advanced question every few days. You're just enabling bad habits. The way forward always starts with a minimal test.	[reply] [d/l] [select]
