I want to evaluate arbitrary Haskell code, and I did start with hs- 
plugins. There are a few problems:

- It doesn't work 100% on Mac (which I'm using).
- It's much slower than GHCi (for each expression to evaluate it  
creates a file and compiles it)
- GHCi has a lot of features that I would have to implement myself  
for hs-plugins (top-level bindings, Control-C handling, lots of  
flags, etc).

But not nearly as fun! :)
