... and erm, how can I enable parsing of optimizer rules? With {-# OPTIONS_GHC -O #-} ?
Yes, although note that Cabal passes -O by default. I'd recommend not putting it in a pragma, as that will break ./Setup configure --disable-optimization
I think the question was how to get the RULES pragmas to be parsed.
I wondered whether it is possible to let the compiler read and store the RULES pragmas without optimizing the code in the same module with respect to these RULES. When I want to compile the code without optimization - for whatever reason - I would still like to have the RULES checked. They could still be applied when imported to another module that is compiled with optimization.
