their long term rate of progress is stable.

What kind of port is this? Direct translation from ruby source?
I see that you are using the (.) for OO-style reversed function
application. Which feels a bit weird at first sight.
Snippet from your Hack.Handler.Kibro:
handle app = do
env - get_env
response - app env .liftIO
-- set
Yes, the spec is almost a direct translation from Rack.
For middleware, I translated some from Rack, but it does not have to
be a port. I'm just lazy.
Rack borrowed some basic middleware from WSGI too, like Lint.
About the style, it's a bit weird, yes. But only in module scope ;)

How so? In future IDEs, source code might just be a view on an internal

If you don't need a 100% pure functional language, and don't need the

in SML -- a purer relative of the more widely-known Ocaml.

However when I did update or insert, I must bind those values, then
