Hello,
I have partial type function which is invoked by another type function. When the inner type function fails with TypeError, outer type function is not been able to propagate that type error to its caller. As a result of it, I'm getting following error • No instance for (KnownSymbol (NestedPartialTF (TypeError ...))) instead of • Unexpected type @ NestedPartialTF: Char
Is this a bug? This behavior seems bit counter-intuitive as to work around, I had to write another (duplicate) type function at the top level to get the desired type error
I'm using GHC-8 RC 3 and have attached complete src for reference.
Regards, Magesh B
