Indeed!  That's the way csh does it.
Example (csh):

	alias   a       alias

	a       b       'cd $b'
	a       cd      'set tmp=$cwd; chdir \!*; echo $cwd; set b=$tmp'

The `cd' in the expansion from `b' will be expanded (upon invokation).
Otherwise I would have to say:

	a       b       'set tmp=$cwd; chdir $b; echo $cwd; set b=$tmp'
	a       cd      'set tmp=$cwd; chdir \!*; echo $cwd; set b=$tmp'

Not nice.
