What kind of profiler are you looking for?
The simplest kind that would have a chance at working across 2 or more implementations. (I know that's a dumb answer but :-} )
There's no standard way to get the current time, so if you want timing, you will need at least SRFI 19.
OK, thanks. That's good info. Perhaps I should look into the MIT and SLIME48 profilers and see if there's something hidden in them that could be made portable, somehow.
Not at all an expert in this area, just wondering if there's something out there my research did not find.
