This is how far I got:<br>
<br>
if I put this right after hs-source-dirs:<br>
<br>
default-extensions: FlexibleInstances<br>
<br>
, it works: ghc asks for MultiParamTypeClasses option.<br>
<br>
However if I add FlexibleInstances, MultiParamTypeClasses<br>
- either separated with comma or on the next line, the compiler parses<br>
.cabal and tries to build however prompts for FlexibleInstances again.<br>
<br>
How would I specify >1 option?<br>
