>> use Irssi 20011211 qw(signal_add command);
Loads the Irssi module, requiring at least version 20011211 and telling
it to export signal_add() and command() into our package.
This kind of version checking came available in the 20011208-snapshot.
Having te Irssi:: subs exported came available in the 20011211-snapshot.
>> sub sig_own
Warns the user: chatting while having windows switch all the time is
foolish, because your text gets sent to whatever window has the focus
when you press enter.
>> signal_add
This was exported into our package, so we can use signal_add() without the
"Irssi::" prefix. Since the 20011207 snapshot, you can add multiple signals
using a single add_signal(). If you want to do so, use a hash reference
(either { foo => bar, foo2 => bar2 } or \%hash).
>> sub { ... }
>> \&subname
These are references to subs(code). The first one is a reference to an
anonymous sub, the second one refers to a named one. Anonymous code
references allow for easy placement of oneliners :)
Irssi understands codereferences since the 20011207 snapshot.
Using references is better than having a string with the function name,
imho.
