Yes, I know.

Frankly, they're both ugly. I personally like the *idea*, I'm not
advocating my solution. It would be wonderful if we could assign values
to Perl's special variables when we're doing a one line quick
hack. Often, I will modify default values in programs in order to be
more lazy. That isn't easily available for a command line hack ( and 80 -
120 characters on the line ( give or take ) ). Why not make it more
available?
And, sure, perhaps the idea bytes, so scratch it. However, I love the
idea of `-f` or something like it, to turn off output buffering.

: Ick.
Just an alternative, I don't like it either, frankly.
