I do think such a feature may be useful if we often work on pieces
of a string delimited by a delimiter, but if the caller does not see
the split result, then the function with "split" is probably

I however suspect the variant of this where "delimiter" can just be
a single byte would not be so useful.

If the input comes from the end user, we certainly would want to
allow "word1 word2\tword3 " as input (i.e. squishing repeated
delimiters into one without introducing an "empty" element, allowing
more than one delimiter characters like SP and HT, and ignoring
leading or trailing runs of delimiter characters).

If the input is generated internally, perhaps we should rethink the
interface between the function that wants to do the for-each-word
and its caller; if the caller wants to pass multiple things to the
callee, it should be able to do so without first having to stuff
these multiple things into a single string, only to force the callee
to use this helper to split them out into individual pieces.
