And just to be a bit safe (anal, possibly), I like to use an absolute path
in my shebang line.

#! /usr/bin/perl -w

Something about horses and Troy....  :-)

BTW -- I remember Damian talking (a few years ago in his ~damian/bin talk,
originally given to SPUG, then later expanded at OSCON) about setting up a
macro in vi (as an emacs user, myself, I don't remember the exact details)
that inserted this shebang line for him.  Personally, I haven't gotten lazy
(the virtue) enough to create such a keybinding in emacs, but I do incant
that magic.

More obvious (to those who don't remember all their powers of 2) 
                        if printed as a binary mask....
$ perl -lwe 'use Fcntl ":mode"; $x=S_IFREG; printf "%b", $x'

Thanks for the example.  I had forgotten (or didn't even know in the first
place) that $mode includes the permission bits *AND* the file type bits.
