- Introduce SourceT, which is simple variant of "correct `ListT`".
There are another variants possible (like in `streaming`),
but I'm not sure there's much real difference.
- Introduce `Codensity`. There's a flag if people don't want to depend
on `kan-extensions`.
- `StreamGenerator` and `ResultStream` are both `SourceT`.
`Stream` combinator in `servant-client` uses `Codensity` for CPS.
- Add servant-machines, servant-conduit, servant-pipes
- Add streaming cookbook: just code, no explanations.
- Add a script to run streaming 'benchmarks'
- WIP: pending http-api-data release
- TODO: remove MIN_VERSION_http_types
- There have been 3 major releases of http-types:
- 0.10 change name of variable
- 0.11 lowercase escaped URIs
- 0.12 uppercase escaped URIs
- It's easier for us to support only latest, migration from 0.9/0.10 to 0.12
is trivial for the downstream. 0.11 may cause semantic (non-type-error) breakage somewhere.
Also allow lens-4.16, remove MIN_VERSION_http_types conditionals, and
update `stack.yaml`
The default Generics-based ToSample instance now uses Omega type
to productively produce distinct samples. The previous version
was based on lists and hence left-recursive. This means that with
previous versions the default toSamples for [Bool] would return an
infinite list like this:
[[],[False],[False,False],[False,False,False],...
As you can see it would never produce a list with True in it.
Omega handles this and produces a more diverse output:
[[],[False],[False,False],[True],...
This is still not the best possible case, but to do better we need
to use Omega not only in GToSample, but in ToSample as well since
GToSample uses ToSample instances recursively.
