Sure. Just use http://hackage.haskell.org/package/haskell-src-meta-0.0.6.
You are probably interested in parsePat or parseExp. I've used parseExp in a
package.

I guess this makes [X] an exponential type, although I don't remember
seeing that term :-)
I would expect the exponential type to be (a - b):
Here's a working example:

No, you're not totally screwed; you just need to bug xmonad-contrib

Using ghci is very important to me, as my programs are pretty high-level and
are often half-liners.
