Taking ideas and integrating them into your own code, absolutely. Copy-pasting non-trivial bits of code into a commercial codebase without proper attribution is not just "bad manners" it is downright illegal and extremely poor behavior.

A few questions arise from that, and since you seem to understand this stuff:

Define non-trivial?
Presumably, copying the word 'if' into my program would require a consultation with the author of the code I took it from?
How about an if condition?
What if I change the variable names?
What about merlyn's is_numeric() function?
```
sub is_numeric {
  ($_[0] & ~ $_[0]) eq "0";
}
[download]
```
Under what circumstances should I take a consultation or negotiate a licence before using that in a commercial Perl project? And how does this affect commercial organisations using CPAN modules as a whole?
Where do you draw the line?
From what you say above, it would suggest that it's the "copy-paste" operation that is the key here?
So, if I re-type the code I wish to use, then it's okay?
At what point do I have to consult with merlyn if I want to use a Swartzian Transform in my code?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
