We found that local extinctions were nonrandom, that changes to community structure (quantified by the species predator/prey ratio) seemed to correspond to local aridification pulses, and that the decline in species rich...

Lazy Assertions

Assertions test expected properties of run-time values without dissrupting the normal working of a program. So in a lazy functional language assertions should be lazy — not forcing evaluation, but only examining what is evaluated by other parts of the program. We describe two different ways of embedding lazy assertions in Haskell, one sequential and the other concurrent. Examples illustrate the...
