Nice. ++.

A variation on the hash-binding theme is to use the contents of the statement handles NAME attributes as the hash keys. Since in most instances you'll be interested in all the keys you are selecting this can be a useful shortcut. For example (untested code):

my $sth = $dbh->prepare( "SELECT foo, bar, ni from some_table" ); $sth->execute; my %row; $sth->bind_columns( \( @row{ @{$sth->{NAME_lc} } } )); while ($sth->fetch) { print "foo = $row{foo}, bar = $row{bar}, ni = $row{ni}\n"; }

In general the NAME attributes of statement handles are useful to avoid duplicating lists of fields in your SQL and in @fields type arrays.

[Eily]: can't the nodelet be moved though? Maybe you could put one that doesn't change first ("Sections" or "Find Nodes" for example)
[Eily]: "Other Users" seems like a poor choice :P
[Eily]: nope, Nodelet Settings doesn't let you move the XP Nodelet, CSS might
[marinersk]: That would mitigate the distraction/jangle issue, but then the information wouldn't be easy to find when it is populated. Plus, I don't currently see a way to move it, but I'm not done poking around on that point yet.
[marinersk]: Ah, you beat me to it.
