Having dealt with equality allowed us to add the missing link between a year of stream fusion development and a new rolling Qi release. Let us have a quick look at what is finally out in the fields and which operations are now optimized!


Finally the changes landed in the main branch with commit Merge pull request #207 from drym-org/define-deforestable-runtime. So just make sure you update your Qi distribution:

raco pkg update qi-lib

After this update you will get many more list operations fused as can be seen in the List Operations part of the documentation.

Hope you liked this little report and see ya next time for more!
