Note that foldl' has a ' to indicate that it's not the same as foldl exactly. I would propose that sum' exist as well as sum, and that sum be lazy.
I wish Haskell allowed ! to occur (non-initially) in alphanum_' identifiers as well as in symbolic ones. Then we could be more consistent about having ! mean strictness like it does with ($!), bang patterns, strict fields,... (too bad about (!) and (!!)). The prime has so many other uses, it's a shame it gets used up for strict/lazy variants, as if there were no other variations.
Yes, a lot of conventions don't always make sense in certain contexts, but at least the convention is there to help keep things consistent (for better or worse) Dave
