Comment (by 4e6):

 I've updated [https://github.com/4e6/webapp-template-hs/tree/simpl-tick-
 factor webapp-template-hs] example (branch ''simpl-tick-factor'') to be
 compatible with GHC 7 and 8.

 With ghc-7.10.3 it compiles with 2534 simplifier ticks, and with ghc-8.2.1
 it panics with 'Simplifier ticks exhausted' on 256649 ticks. See readme
 for details.

 Here is the full `-ddump-simpl-stats` output for both cases:
