One minor nit: You missed a way to get a false-but-defined value. It's possible if you've set $/=\1, that is, if you're reading a byte at a time.
One minor nit: that won't work, I quote perldoc perlop
In these loop constructs, the assigned value (whether assignment is automatic or explicit) is then tested to see whether it is defined. The defined test avoids problems where line has a string value that would be treated as false by Perl, for example a "" or a "0" with no trailing newline. If you really mean for such values to terminate the loop, they should be tested for explicitly:
You can test if you need convincing ;) 
E:\>perl
$|=1;
$/=\1;
print "[$_]" while <>;
__END__

update:
theorbtwo: that was my point, defined is implicit, so it wouldn't matter if it was false
sauoq: I was not responding to the entire meditation, but to theorbtwos response. I do not consider using while(defined($_=<>)) a meme.

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
