The supposedly parallel version isn't needed in my experience if there is `let*', which there is, _but_ the minimalist attitude of programming will make it look wierd - hey, why is let* here, when there is no dependent binding? Maybe `let' will truly be parallel one day and then all old software keeping a strict division between let and let* will be rewarded :) BOOM ... and they are just gone -- underground experts united http://user.it.uu.se/~embe8573 https://dataswamp.org/~incal
