Giving an instance for \haskelllhstexinline{Interp} for \haskelllhstexinline{DataType} that uses the extensions \haskelllhstexinline{e_1, e2, ...} and depends on interpretations \haskelllhstexinline{i_1,i_2, ...} is done as follows:
\begin{lstHaskellLhstex}
-instance ( UsingExt '[e_1, e_2, ...] s
- , DependsOn '[i_1, i_2, ...] s
- ) => Interp (DataType s) where
+instance ( UsingExt '[e_1, e_2, ...] s, DependsOn '[i_1, i_2, ...] s)
+ => Interp (DataType s) where
...
\end{lstHaskellLhstex}
