The bad news is that i hadn't realized that Racket's current-load/use-compiled is not exported and i cannot call it directly (that explains why my own version). The not so bad news is that the problem is actually in Racket, not in Geiser. If i try Racket's enter! in a vanilla racket session i get: $ ./racket Welcome to Racket v5.3.0.21. > (enter! slideshow/pict) define-values: assignment disallowed; cannot re-define a constant constant: invoke-unit/core in module: "/home/jao/src/racket/collects/racket/unit.rkt" > So it's also a problem with current-load/use-compiled (as to why in Geiser a require uses also the latter, it's because Geiser needs to keep track of all modules as they're loaded, and i didn't find any hook to get notified of those events...).
