SPUG: -MO=Deparse; what it is?

[Tim Maher/CONSULTIX]

(E-)?SPUG-ticians,

In a Perl Beautification discussion I had with somebody,
the following -MO=Deparse business came up.  Does anybody
know what this is?  (My O'Reilly bookshelf seems mute on
the subject, and the person who brought this up has long
since "gone out of scope" (mine, not his)).

It sure gives interesting output, but I wouldn't call it
a beautifier; it's more like an overzealous copy-editor!

$ perl -n -e '1 .. 10 and print;' /etc/motd
Linux 2.0.36. (POSIX).

$ perl -MO=Deparse -n -e '1 .. 10 and print;' /etc/motd
-e syntax OK
LINE: while (defined($_ = <ARGV>)) {
    print $_ if 1 .. 10;
}
$
