in thread sql select with array

I'm interested to know why you think that changing $" is a "questionable" solution. It seems to me that it's situations like this that $" was invented for.

    I would say it "questionable" as well. (And I use it all the time. :-) Three reasons.
    1. I try to avoid global variables as much as possible.
    2. $" is line noise and accordingly easy to miss by a maintainer (who is most likely not at my level of perl).
    3. Beginners are much more likely to set global variables than to localize them.
    (4. $" screws up the syntax highlighting in many editors.)

    Join() performs the same task in a much more maintainable way, so its not really needed. Also, if you think about it join is about the same or less in terms of usage.

    local $"=','; my $s="@list";
my $s=join(',',@list);

    As i said though I use it in obfus, snippets and temporary debuging code all the time. But only cause I like to. :-)

    I always hesitate to tell anonymonks to go tinkering with global vars..... Its the case of "a little information can be dangerous." Once you understand the full implications, I think it is a fine solution, though.
