    v185 v186  
    5252
    5353=== Other performance ===
     54 * #5028: extra `let x=y` binding left around after `CorePrep`
    5455 * #605: strict/unboxed enumerations
    5556 * #2607: space leak: inlining defeats selector thunk optimisation
     
    5960 * #2988: better float-in
    6061 * #2940: do CSE after `CorePrep`
    61  * #2670: record selectors behaving badly wrt optimisation
    62  * #1434: Slow conversion Double to Int
    6362 * #2132: Optimise nested comparisons: if you know x>0 then you know x>=1 etc.  Maybe a special pass that knows about arithmetic?       
    6463 * #149: float-out/CSE 
    6564 * #2289, #2387, #1600: nested CPR analysis     
    66  * #2092: Possible quadratic-sized Eq instances. Does it really go quadratic, or does the join-point inlining machinery prevent it?  Still to check: delicacy wrt case-of-case
    6765 * #2255, #3767, #2642, #3831, #4941: Improve '''`SpecConstr`''' for free variables, and for join points.
    6866 * #2374: SAT and `MutableByteArray`    Max?
