Document that uniq keeps the last duplicate #214
Description
Activity
If it is unstable, this should at least be documented.
I'd prefer things like this be documented to be unstable so that people aren't expected to memorize which behavior functions like these have when they're reading code using them. Instead of supporting the use of a surprise
Eqinstance via functions likeuniq, functions that were explicit about their behavior and were parameterized over a relation that didn't have the implicit baggage ofEqwould be much more appropriate.- added a commit that references this issue

The documentation of uniq does not specify exactly which elements are kept.
This is important when Eq instances do not consider all parts of the data structure.
Do you think this should be documented (and tested), or should this be left unstable?
