[ANN] interval-patterns-0.8.2

Mixfix (heehee) operators are hard to do in Haskell, which is why I stuck with infix ((:||:) and friends). It would be interesting to see this design space explored, but I think even with -XPostfixOperators you would need parentheses like ⟦ 2 (5 ⟧) to be able to express them properly.
