I like that idea - and it seems to fit neatly with the existing
partition contract: the inclusion of the matched-delimiter as an item
in the result-tuple would reduce match ambiguity (rationale: imagining
a use case where a caller would like to provide multiple delimiters
during method invocation, and then subsequently check which delimiter
was used at a given match position).
Since it's both orthogonal to (does not depend-on, nor is it a
dependency-of) multiple-partition-arguments and composible with (can
be combined with) multiple-partition-arguments, perhaps it should be
advocated-for as a separate proposal? (rationale: that would allow
either proposal to advance without delaying the other -- bearing in
mind a hopefully-unlikely chance of merge conflicts if they reach
release-readiness implementation status in parallel)
