....and then takes 60 lines to do it.  A bit long winded :-)

Almost.  You have to be careful if you have more than 9 arguments....

	$ set a b c d e f g h i j k l m n o p q r s t u v w x y z
	$ eval "echo \$$#"
	b6

b6?  yup....  it turns into echo $26, which is parsed as ${2}6.  To
get around this, one needs some more {}'s:

	$ eval echo \$\{$#\}
	z

Still, very ugly :-)  Any other takers on this one?
