Having an easy way to write unit tests would be great. I made an attempt to do this during my internship (this wasn't merged): https://github.com/jstolarek/testsuite/blob/0829be3a00eecfab0d7026c9a5dc18dc... https://github.com/jstolarek/testsuite/blob/0829be3a00eecfab0d7026c9a5dc18dc... But that is far from a real unit test: results of many unit tests coupled together in one stdout file, lots of boilerplate and reinventing the wheel. I would love to see the testsuite extended with an easy way to write unit tests but I guess that might require some substantial effort.
PS: I’m subscribed to the list, no need to send a copy to my private address. This is typically done to alert someone that he/she has been addressed directly in a discussion. I for example have my filters set in such a way that all ghc-devs mails are automatically marked as read unless I am CC'd.
