Fast Map Union and Local Instances Through Instance Types
1 project | /r/haskell | 26 Feb 2023

Interestingly, the reflection docs give a similar example, though this one uses a newtype instead of directly using the instance (you could do the same with the unsafeCoerce version).
Faking Local Instances with unsafeCoerce Dict
1 project | /r/haskell | 18 Mar 2022

Altough after looking at the reflection examples for local instances, it seems like reflection still needs some kind of 'carrier' newtype (M and Lift in the examples), so you don't get full local instances in the same way you do with my library?
