Definitely not a method on lists, we agree on that.  Problem is, there
is no module in the standard library to collect "functions that are often
useful but not QUITE often enough to warrant being built-ins" (and if
there was, there are quite a few current built-ins I'd like to relegate
into such an auxiliary/utilities module), so that finding a good place,
other than built-ins, for such utility functions, is often a bother.
