Yeah, I guess it could certainly be made simpler or shorter, but you don't say how. Please, tell me what you have in mind. I'm often tying to make concise solutions, but, at the same time, I'm not too much...

Perl Weekly Challenge 130: Odd Number and Binary Search Tree
This does more allocations and deallocations, potentially many more, so it will be slower in a lot of cases – in most, I’d even say. The memory savings will only be significant if the list of integers is very large and the mean count of occurrences is very small – and even in that case it depends on the mean distance of occurrences being small, otherwise lots of keys will be kept around at any given time anyway.
