IIRC, Arc/HN runs on mzscheme because they rely on mutable cons cells that newer versions (racket) don't provide. Could they run under new rackets by just telling racket to use a proper scheme?
- moron4hire 14y agoThere is an mzscheme language mode, but it specifically does not include set-car! and set-cdr!.
