Talk:Lucky and even lucky numbers

Wrong example of even luckies?

take a list of all the positive even integers

2, 4, 6, 8, 10, ...

remove every 2nd number

2, 6, 10, ...

take the 2nd number (which is 4 )

Not 6?

I had a question that wasn't relevant once I understood the task more so deleted it almost immediately. --Paddy3118 (talk) 11:50, 9 March 2014 (UTC)

What does "Mixed case should be supported" mean?

This phrase can be read in diametrically opposite ways. I took it to mean that it doesn't matter what case you type the argument, which means the prior rule about spelling would only care if you had the wrong letters, not the wrong case. By this interpretation the Perl 6 entry is not incorrect in its argument handling, and the example is merely demonstrating case insensitivity. If this is not the intended meaning of "mixed case", it needs to be clarified in terms of case sensitivity vs insensitivity. Perhaps my intepretation is colored by my absolute loathing of "camel case" words, which I think have no place in a task such as this, if indeed they are being considered mandatory. It's quite challenging enough to meet the numeric challenges of this task without all the extra API folderol, in my estimation. --TimToady (talk) 01:09, 10 March 2014 (UTC)

(Also, if the quibble is that Perl 6 entry isn't following the first three rules, it is. It is, in fact, testing for those conditions with the signature matching. If the intent is to mandate some kind of particular error message in response to those errors, it should be made clearer just how anally the original implementation is to be copied.) --TimToady (talk) 01:24, 10 March 2014 (UTC)

(Or if the requirement is for a placeholder comma, it's certainly not necessary for the Perl 6 solution, though I could certainly make it throw one away easily enough. The point of Rosettacode is to show idiomatic usages, not force every language to show how it supports the limitations of other languages...) --TimToady (talk) 01:42, 10 March 2014 (UTC)
