How do people use this stuff? The README is empty, there's no
documentation, and none of the functions are commented. I'm forced to
conclude that there are people capable of looking at this,
createPoolCheckAlive :: MonadControlIO m
=> IO a
-> (a -> IO ())
-> Int
-> (Pool a -> m b)
-> (a -> IO Bool)
-> m b
and knowing immediately what it does.
I'm still a beginner, and I don't think I have a use for this package
(what does it do?), but I've run into similar situations with other
packages and would genuinely like to know (as opposed to just complain
about it).
