These aren't the same.
The ksh `$_' is the final argument *after* globbing,
while the csh `$!' is the final argument *before* globbing.  e.g.,

a directory contains the following:

foo	bar	foobar

In csh:
	% echo *
	foo bar foobar
	% echo !$
	echo *
	foo bar foobar

In ksh:
	$ echo *
	foo bar foobar
	$ echo $_
	foobar
