Maybe some means of asserting that a rule is applied? Hopefully by
effect (this list should not appear in the core, or whatnot) rather
than by naming the particular rule...

For performance-critical code, it seems sensible for me to stick to my `forLoop` for now, as it works quite well with the existing GHCs and much less brain seems to be necessary to get that compile down to fast code.
I agree. I think one big problem is that RULES (e.g. list fusion) are great when they work, but it is very hard for the “normal” Haskell programmer to confirm that they work as expected, let alone predict when they work. I don’t have a good solution, though.
Greetings, Joachim
