RWH suddenly started using runhaskell instead of runghc. What's the difference? As far as I can tell, they work the same.

<code>runhaskell</code> can run whatever Haskell interpreter you're using on your system—it does not necessarily have to be GHCi. For example, <code>runhaskell</code> could instead point to <code>runhugs</code> or <code>runjhc</code> or whatever, if appropriate. Essentially, it's just a nice alias. By using it, you make it much easier to change which compiler you're using in the future. After all, having <code>runghc</code> run <code>jhc</code> instead would be confusing!
