It's worth pointing out that there's a bit of bang-pattern mysticism going on in this conversation (which has not been uncommon of late!). A non-buggy strictness analyzer should expose the strictness of these functions without difficulty.

Could the result of strictness analysis reported in terms of the original Haskell program?

  > ghc -O2 -ddump-strictness test.hs

  test.hs:3:1:
      Top-level function `foo' is found to be strict in the
      first and third argument.

This could help people gain confidence in the strictness analyzer.
