Comment (by RyanGlScott):

 FWIW, `aeson` has resolved this upstream by increasing the `simpl-tick-
 factor` to 200 for that particular benchmark (see
 [https://github.com/bos/aeson/issues/502 this issue], and
 [https://github.com/bos/aeson/commit/35ae44dbec513b45d4ec94d95588c56d35b7f88a
 #diff-2f38c1adee324e73bf376a514fd4a3ae this commit]).

 I slightly reduced the
 [https://github.com/bos/aeson/issues/502#issuecomment-269911373 test case]
 here, but I do ultimately think that overly aggressive `INLINE`-ing is the
 culprit here.
