I think that's a bit of an exaggeration. A hypothetical each()
function would almost always be at the end of a UFCS chain,
making it clear that it's iterating and consuming the result.
This is no worse than putting .array at the end of a chain to
force evaluation (and is actually much clearer about intent).
