[Haskell-cafe] Re: Why is this strict in its arguments? (Jules Bean)

[John Lato]

Wow, thanks.  I had a similar function (long if/then/else chain,
fromJust) that I haven't been happy with, but couldn't see how to
improve it.  Now I have a much better idea for how to fix that
function.
Thanks again,
John Lato
