I already got used to TH a bit, but I am not sure if it is appropriate
for my purpose, or at least not completely.
I want to load Haskell code into my program at runtime in an abstract
representation (as TH), modify it and then type-check it or coerce it
into a value (or execute it). For me it looks like I need a combination
of Hint and TH.
However, Hint can only interpret strings and to get a string from a QExp
I have to enter the IO Monad using runQ. So, wouldn't it deteriorate my
performance to do it all in the IO? Is there another way?
