Robby Findler 38f5823a59 adjust plai's gc2 language to use roots as the arguments ... to gc:cons and gc:closure instead of passing locs This enables the important change, namely that get-root-set no longer returns roots corresponding to the arguments of the allocation function that we're in the middle of. This means that a common error students have (forgetting to chase the 'hd' and 'tl' pointers in their GC) is harder to make now, since get-root-set never contains those locations as roots. (In the past you would have had to write some pretty non-obvious mutator program to get that behavior.)		2013-03-09 16:08:00 -06:00
