Is there a function for this?

Remembering that uniq works with a custom predicate, which should be 
sufficient in most of those case.

Same for sort: works with a custom predicate.

Yes, it can be inconvenient but I'm under the impression that making 
algorithmic complexity a property of a function is agreed by most 
people. (For D, algorithmic complexity is in the documentations of 
functions; alas, uniq lacks it.) So, it's a good thing that we know that 
uniq is always O(N).
