princepawn has asked for the wisdom of the Perl Monks concerning the following question:

I typed $" into the search engine to find out how it related to takshaka's soln to a file inserting spurious whitespace at the start of each line but did not see anything... so : maybe this should show up in the search engine and: can anyone tell me what this is?

    $" is the list separator string. All the special variables are described in the perlvar manpage.

    the default value of $" is ' ' (space), so printing it might be deceptive. $" is the array print separator, so consider the following code: 
    {
    local $" = ', ';
    @a = qw(foo bar baz quux);
    print "@a\n";
}

    which outputs: foo, bar, baz, quux
