[...] In most cases, you'll get recomputation, but GHC does a bit of CSE, so in some cases it will compute only once and share the result (which may be a bad thing - that's a further reason for not doing too much CSE, sometimes sharing has catastrophic results).
This is a beginner's list, so I'll ask: what catastrophic result could it have, if it's computing pure functions?
