I'm looking at iteratee as a way to replace my erroneous and really
inefficient lazy-IO-based backend for an expect like Monad DSL I've
been working for about 6 months or so now on and off.
The problem is I want something like:

PHPProxy is a web based proxy. To use it, you have to type the http
address you want in a field on the page.
You still need some web access in order to access a web-based proxy...

Today I stuck with the following problem: I want to read a file with
iteratee package, and but it to database through Takusen package, but
it doesn't work. The `Takusen` was built with `mtl` package, and
`iteratee` - with `transformers`, so they are conflicting when used
simultaneously.
And
after updating to cabal-install-0.8.0/Cabal-1.8.0.2 with GHC 6.10.4, I
always get an error when updating the package list:
cabal update

Well, `Seek' is not an error message. It is one of constructors for

* make `inferior-haskell-find-project-root' respect export lists
I am writing a binary data parser and use `iteratee' package.
The following pattern appears quite often in my code:
results - map someConversion `liftM` replicateM nbytes Iter.head
The meaning is: take `nbytes' from stream, apply `someConversion' to
every byte and return the list of `results'.

for installing Hackage packages -- cannot work with HTTP proxies.
Despite all the necessary code linked in.
