It'd be nice if there were no restrictions on module names when yogurt loads a 
module.

Right now the module name must match the filename (e.g. module Foo in Foo.hs) 
because Hint 
provides no API for finding out what the name of the loaded module is.

Opening the following session causes a bus error on my machine:

custard :: Session
custard = session
  { hostName = "localhost"
  , portNumber = 5678
  , mudProgram = \reload -> echoln "Boom!"
  }

Calling echo* within hooks seems fine, as does echo* outside of hooks while 
reloading.

Yogurt should better handle SIGINT and local EOF.

What steps will reproduce the problem?

1. cabal install Yogurt -freadline
2. cabal install Yogurt-Standalone
or
1. cabal install Yogurt -f-readline (this works)
2. cabal install Yogurt-Standalone (this fails)


What is the expected output? What do you see instead?

configure: error: readline not found, so this package cannot be built
See `config.log' for more details.
cabal.exe: Error: some packages failed to install:
Yogurt-0.4 depends on readline-1.0.1.0 which failed to install.
Yogurt-Standalone-0.4 depends on readline-1.0.1.0 which failed to install.
readline-1.0.1.0 failed during the configure step. The exception was:
ExitFailure 1


What version of the product are you using? On what operating system?

Haskell Platform 2010.1.0.0, Windows 7 x64, MinGW 5.1.6, and MSYS 1.0.


Please provide any additional information below.

I realize that this isn't strictly a bug with Yogurt, but I was hoping that you 
could offer some advice on how to get it compiling (or point me in the right 
direction). Thanks.
