What's the motive for using -> when there's only one form after the expression? I get why you'd do it with two or more forms - it reduces the nesting, and reading left-to right follows the evaluation order. But with just one form it's liable to have the opposite effect on nesting, and it makes the evaluation order read zig-zag. <mike -- Mike Meyer <[email protected]> http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information.
