[Haskell-cafe] RE: Random matrices

Ah ha. That'll do. Lesson: avoid hidden space leaks in monads.

Hmm, I'm still missing something. It seems a good lesson, but practically speaking, it doesn't help me any more than saying "write efficient programs". What could I have looked for in the original code to predict it may be leaky? Is there a way of thinking about this that can help me stop hitting space leaks like this? BTW, I really do appreciate the help. I've been amazed at the level of effort put forth by the Haskell community as a whole to help out newcomers. -Chad
