Well, it's not really data mining but I wrote a program that would list the interests my friends have, ordered by the popularity of the given interest. As far as I can tell, LJ does not have robust tools for gathering said data, so I was forced to resort to HTML parsing. Yuck. The program has bugs, but it was a fun little exercise. I ran it for a friend of mine and curiously, he discovered that the most common interest for his friends was "cats", but he's not particularly fond of them. I, on the other hand, have a rather large number of friends interested in piercing, corsets, and candles (not the top interests, though.) I'll not speculate as to what that means.

Thanks. I saw that in someone else's code and I realized that my has a return value: the variable that it's declaring. This is not exactly clear from the docs, though. Maybe I should submit a doc patch. Hmm.

I like using it as part of an if statement:if (my $foo = bar()) {
print "I got $foo\n";
}-Dom

I like the idiom but I've always been disapointed you can't write:if (my $foo = bar() and $foo =~/bar/) {
print "\$foo is bar\n";
}Re:Cool DRY-inspired idiom

You can't do that because the variable doesn't come into scope until after the current statement finishes executing. Fortunately, that's an easy fix.
perl -le 'sub bar{ "baz" };if ((my $x = bar())=~/baz/){ print "yes" }'Re:Cool DRY-inspired idiom

The problem is that that causes a warning if bar() returns undef.
