Me again! after removing some libraries, my project now depends on:

- containers
- mtl
- transformers
- singletons
- singletons-base
- parsec

Nevertheless, since I’m using `ghc-wasm-meta`, I cannot really include the singletons-base package (since it depends on `th-orphans` and the WASM backend doesn’t support TH yet).

I might be able to patch things up, if I can just expand the TH definitions in the singletons-base package, but I don’t really know how to do this without just forking the repo, running cabal build with `-ddump-splices -ddump-to-file` flags, and manually deleting the `_XXXX` identifiers.

Is there a better way to do this?

Wow! I wouldn’t have even considered this to be a possible issue. Thanks for pointing it out to me.

It totally seems like a language frontend thing that would be completed before even core was generated.
