  • This is a comment from another French monger which doesn't have an account on user.Perl yet, and asked for someone to post it. So here it is.


    Well, I'm also a French native speaker and I must admit that I too made this mistake when I first learnt Perl, but I had to accept that "$" had to be used to access a single element and "@" to access the whole array. Actually, Perl's scalar and lists contexts still aren't really clear to me but the more I write Perl, the more I get used to it. I don't even try to understand why I have to do so, which may be a bad behaviour, but I came to just know when I must use this or that.

    But, now I consider what you wrote, I now *know* that I should use "@" to use a slice, but then, what is the difference between the single value $array[$i] and the single element slice @array[$i] ? This particular example shows the problem when trying to adapt a thought language to a naturally evolved language such as French. I can't think of such a plural in French. Or maybe "une paire de ciseaux" which would equal the English "a pair of trousers", but that's become a kind of evolution of an exception and isn't a general rule.

    On the other hand, I also speak Japanese, which is a language without plural, and this "$/@" stuff might be the reason why a Japanese guy invented Ruby :) Moreover, learning such a different language such as Japanese has taught me to admit rules at first sight, and then to try to understand them if I ever see an etymological explaination or how Perl manipulates this in its core. But for this, one needs a lot of knowledge of the language....

    I hope that it answers your question,

    Sincerely, Axioplase
