Similarly, please see https://ghc.haskell.org/trac/ghc/ticket/12032
for a regression when using many top-level cases in equational style.
I haven't looked at core, it's possible this issue is the same as
ticket 12028.
Also please note I am _not_ on the -dev list at present so that list
is not

Please see
It also helped that the test suite got added back to the main cabal. And
the test suite took a WHILE, due to some sort of coercion seize blowup that
I think was fixed in 8,0. But yes. Definitely vector build times decayed.
Partly due to the shift to the general bundle rep, and partly due to ...

The vector package is probably a good candidate. Compling vector slowed
tl;dr. Do you have a Haskell project which GHC now compiles more slowly
than in the past? If you would like to see your program's
compilation time improve in 8.2, reduce it to a minimal testcase,
and provide it to us via Trac.
Good news everyone,
GHC 8.2 will be a release
