From the keyboard of okamoto@hpcc01.HP.COM (Jeff Okamoto):
:I'm trying to get the .. construct to work when it is passed in as a command
:line argument.  What I am having trouble with is getting the .. to properly
:expand.  I've tried a bunch of ways to force the result into an array context,
:but I'm obviously doing something wrong.
:
:I've tried a number of variations on the following, to no avail:
:
:	$a = "'A0'..'A9'"; # Eventually will be shift(@ARGV);
:
:	eval "\@b = (\$a)";
:
:Can anyone offer any suggestions?

I'm not sure why you're going through the eval.  I would just use:

    @b = 'A0' .. 'A9';

and be done with it.  If for some reason you must use the eval
way, remove the 2nd backslash:

:	eval "\@b = ($a)";
