Some will, yes.
For example, the natural and naive way to write Andrew's "mean" function
doesn't involve tuples at all: simply tail recurse with two accumulator
parameters, and compute the mean at the end. GHC's strictness analyser
does the right thing with this, so there's no need for seq, $!, or the
like. It's about 3 lines of code.
