I'd expect list comprehensions to work significantly faster than
equivalent expressions using filter, map and lambdas - the reason
being that the overhead of repeatedly calling the lambda should be
avoided, not to mention avoiding the temp storage between the filter
and map.

I haven't tried this, but it might be worth a go.
