I'm not sure where we have different definitions in mind; surely it can't be
controversial that web application containers are far more complex than most
other libraries.  Just look at the dependencies on any such project.  I'd
call it a fair statement that no one thought the problems of Cabal scaling
to very large numbers of packages was much of a problem until web frameworks
started being a big deal.  It also seems rather non-controversial to point
out that Yesod includes a lot more here than other options; the Snap
project, for example, happily proclaims itself to work at a level of
abstraction analogous to servlets, and currently makes no attempt at solving
persistence, form handling, and such.

In any case, sorry if that sounded like sullying the "good name" of Yesod.
I didn't even think it was particularly controversial.

Yes, that's precisely my point.  I can think of very few other domains of
Haskell programming where having not used a specific library even if you're
familiar with the kind of problem it solves causes discussion about that
library to look about as meaningful as ancient heiroglyphics.  OpenGL would
be one, as well as GHC internals.  I'm having trouble finding other

Again, this isn't a dig at Yesod... I don't think *anyone* has found a good
way to build a web application framework that's both simple and obvious to
understand and solves the hard problems.  I think it's at least partly
endemic to the problem domain.
