[REBOL] Re: Set on path values

From: rudolf:meijer:telenet:be at: 13-Aug-2007 12:27

Hi Gregg, Thanks! This worked first time around. I was apprehensive of the binding of the expressions to be evaluated as path members, but this was fine. Is that the magic of [do val]? Rudolf RWM> Does anyone have a suggestion for a one-argument function that will do RWM> [suit-size/:hand/:suit: suit-size/:hand/:suit + 1] just like incr cnt RWM> would do [cnt: cnt + 1]? Something like this? incr: func ['val] [do reduce [to set-path! :val 1 + do val]] -- Gregg
