in thread Want for a name?
Well, mentioning the plural brings a new perspective...
For me designing and naming a good API is far more complicated than coding, since it involves human psychology.
Especially since sometimes good names are already used or even only reserved.
This brings a new concern, wasting an otherwise better used word.
overlaps could mean much more things and especially in plural it could indicate tuples bigger than just a pair of values.
The English grammar has no dualis alongside singular and plural like for instance Arabic, so only constructs like pair or couple indicate 2 tuples, and couples are normally disjoint. Maybe a construct with prefix "bi-" could solve this (think bigamie ;-)
Other than describing the tuple as a whole one could try describing the relation between two elements.
So my best guess ATM is "neighbor" but in singular(!). The neighbor can't mean anything else it describes a relation between 2 objects.
Words like next or link already have different meaning and bichain sounds artificial in my ears.¹
Otherwise I would consider successor or one of the synonyms like follower or one of it's synonyms like companion.
As soon as the definition is clear seeking through a thesaurus is of help.
