-Wall? The number of -W options enabled should scale (at least) linearly with code size.

To make this a little more clear:

You should probably be using the -Wall compiler option, which will produce a message for code constructs that the compiler finds suspicious.

In your case you should see three relevant warnings:

1. "moverFromWord8s" is defined but not used 2. "moverFromWord8s" has no explicit type signature 3. "movesFromWord8s" has a non-exhaustive pattern match

And that warning #3 is the one that you really should care about. It'll save you. -- John
