Hello.

I have got next problem: I want to have database connection pool in server based on network-conduit. So I wanted to be able to do

...

runTCPServer options action   where     action src snk =       pool <- ask       ....

In this situation I can make pool `action's parameter, but in more difficult situations (many methods inside) is would be painfull.

Also I wanted to have some kind of State for each thread, e.g.

...

action src snk = src $= act1 $= act2 $= act3 $$ snk

in act1, act2, act3 I want to read and change state.

Is it possible? And how to do it if it is?

It should just be a matter of relaxing the type signatures in network-conduit. I'll include that in the next release.
