Summary:
I'm using this to test variants of the monad. In particular, the
current monad displays O(n^2) performance with the seql version of
this benchmark. This is a well-studied problem, see for example
"Reflection without remorse: revealing a hidden sequence to speed up
monadic reflection" (van der Ploeg / Kiselyov, Haskell '14)
Test Plan:
Built it and ran it a few times
unit tests still work

The function performFetches collects statistics about the requests
performed in each round. However, the list is not evaluated (unless
tracing is on), leading to an accumulation of thunks. Forcing the list
via deepseq prevents this.
Summary:
Haxl.Core.Env and Haxl.Core.Fetch were collapsed into Haxl.Core.Monad in
D1427283. Update haxl.cabal to reflect this and use PatternGuards to
suppress warnings.
Test Plan: ~/local/haxl-github $ cabal test
