That sentence was regarding the post of @sgraf (citing it: `So, the fix to apply in your situation seems to be to eta-expand test1 and omit the INLINE pragma.`) :) Yes, making GHC always listen to INLINE will help me regarding 2,3,4! 5. This is very interesting. Would you be so nice and tell me jsut a little more aobut it - where can I learn about it and why such design decisions were made? 6. :) 7. Very interesting. Thank you for sharing the knowledge! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15519#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
