Four characters. Six, if you also rip out the parentheses. :-)

Seriously, it's not just about saving one system call or half a dozen source code chars (altough I am all in favour of both) -- -d $filename && -x _ && -k _ && -u _ is simpler, cleaner, and more expressive than the alternative IMHO.

BTW, I happen to like even more the perl6ish $filename ~~ :d & :x & :k & :u.
