OK, so I'm pretty sure I'm not the first person to run into this... I've got a fairly large, complex program. It seems to work fine. But now I want to add some counters to measure various things. Trouble is, to do that, I'd have to "infect" the entire program with boilerplate code to propogate these counters. At best I could wrap it up in a monad, but it's still annoying to have to make 90% of the code in the program monadic just to carry these performance counters around. Does anybody know of a better solution? I could use the dreaded unsafePerformIO to prod some IORefs, but now you have to start sprinkling NOINLINE pragmas around and hope you know what you're doing... Scary! o_O
