The documentation (Patches.md) says ".. way we can play the patches with real MIDI-device:" ``` dac $ mul 0.75 $ atMidi toneWheelOrgan ``` but on my machine this fails with...

build error: vm check failed: is_composite(o)

Hi. Building from source (git tag v3.4.2) on fedora-linux x86_64 with gcc-9.2.1, following instructions (using cmake then make) fails with ``` lean/library/init/meta/relation_tactics.lean: parsing at line 12terminate called after throwing an...

slow compilation

3

Hi. This library is very slow to compile? With ghc-8.10.2, compiling hip-1.5.6.0 from hackage takes more than 10 minutes total (some modules take 5 min), on an otherwise reasonable machine...

Data.Sequence time bounds: emphasize (stronger) that they are amortized?

1

All time bounds are amortized (as in the Hinze/Paterson paper) but API docs mention that word only once "An amortized running time is given for each operation". A casual reader...

CI fails for ghc-8.0.2, because of basement-0.0.13

looks like this https://github.com/haskell/containers/runs/5517053088?check_suite_focus=true and the reason seems to be https://github.com/haskell-foundation/foundation/issues/561 I could reproduce this locally, and fix by adding `--constraint 'basement

Larger keys for intmap and intset

15

as discussed in https://github.com/haskell/containers/issues/788 . I have no idea on how to best pass the "-a N" option for testing. Does it go in haskell-ci.yml, or in cabal.haskell-ci? or in...

user larger keys for IntMap tests

8

Prompted by https://github.com/haskell/containers/issues/787#issuecomment-884565646, I replaced the Arbitrary instance with ``` instance Arbitrary a => Arbitrary (IntMap a) where arbitrary = fmap (fromList . fmap (\(k,v) -> (getLarge k, v))) arbitrary...

improve benchmarks for Data.IntMap

9

Benchmarks should * use several sets of data (currently: just one, contiguous keys `[1 .. 2^12]`) * test bulk operations (union, intersection) - currently, they don't? https://github.com/haskell/containers/blob/master/containers-tests/benchmarks/IntMap.hs NB: these bulk...

possible performance benchmark for IntMap

5

Dear maintainers, I have an application that could be made into a performance benchmark for IntMap. It is similar to what fgl (functional graph library) does, but for a specific...

"implementation is left-biased" - but fromList(With) is not

2

The actual behaviour of `fromListWith` surprised me, given the general "left-biased" feeling of the library. I think I was expecting that these be equivalent ``` fromListWith (++) [ (0,"foo"), (1,"bar"),...
