Okay, got it. But R6RS custom ports were designed around the port operations available in R6RS. If the editors had decided to use SRFI 6 ports, there probably would have been an 'extract' operation in custom output ports. This, by the way, is why I'm not planning to propose a custom port abstraction for R7RS-large. There are lots of different kinds of ports in the wider Scheme world, and every one has some extensions or restrictions that would have to be taken account of in a custom-port scheme in order to make it really universal. -- John Cowan http://www.ccil.org/~cowan co...@ccil.org Monday we watch-a Firefly's house, but he no come out. He wasn't home. Tuesday we go to the ball game, but he fool us. He no show up. Wednesday he go to the ball game, and we fool him. We no show up. Thursday was a double-header. Nobody show up. Friday it rained all day. There was no ball game, so we stayed home and we listened to it on-a the radio. --Chicolini _______________________________________________ Scheme-reports mailing list Scheme-reports@scheme-reports.org http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
