Clearly, http-enumerator is the best package for doing http/https. however
since it's pretty new, lots of package still uses their own abstraction for
doing things.

While it may be possible to retrofit hoauth to use http-enumerator, using the
httpclient typeclass, that's going to be hard to fit the full enumerator
interface on it, so you won't benefit of streaming; You may as well just use
network.curl for now, which is what i've seen used with hoauth.

you should check the twidge twitter utility and/or yesod-auth-oauth, that both
uses curl/hoauth.

It would be really useful to see an hoauth fully using enumerator and
http-enumerator (and not redefining a boat load of stuff), but IMO you'll need
to understand enumerators before tackling such a challenge.

Also Wai is for abstracting server side "transport" (cgi/fastcgi/others), and
the HTTP package doesn't do TLS.
