You can keep an index and a count instead of a slice.
If you know your data well, you can exploit this knowledge, and 
this has the potential to save you many bytes per "slice" when 
dealing with large data sets.
Depending on your access patterns, it also has the potential to 
be fairly more cpu-efficient.
