I’ll take a look, thanks! My biggest concern with Scheme is that each implementation seems to have its own ecosystem due to subtle incompatibilities.
From an outsider’s perspective it seems a lot more fragmented than CL. Not necessarily a big deal if you have the libraries you want, but it gives me pause.
R7RS, which Gambit (mostly?) supports, helps mitigate this by making library code more portable across implementations. Gambit, in particular, can also very easily take advantage of the wide variety of C libraries; it has one of the easiest, most integrated FFIs of all Scheme implementations.
