 Why in the world isn't ``which'' written as a csh shell script??

Most probably because C shell scripts should be avoided at any
cost.

 There's a real reason for not writing this in csh.  Because the
 built-in function will return results for csh, which might not be the
 right ones for other shells.
 
I got bitten by this by HP-UX 10's csh-based "which". My solaris-hosted
NFS home directory had the default Solaris .cshrc that changes $path.
Needless to say, "which" was somewhat misleading :-)
Ugh.
