Just out of curiousity, are you adding explicit type annotations? I imagine
that type inference (rather than just checking) would add considerable
overhead in pathological cases, especially if GHC is using a SAT-solver
based approach (which I believe it is, these days).
Yes. Every cell is a top level function with a type annotation. All cells
have the same type.
I was afraid that splitting the module doesn't help.
