ints work as slice endpoints just fine. They will get cast to size_t 
when used for slicing.

If you are going to keep the mark valid, you shouldn't slice away the 
input, because now 0 becomes the point at the mark.

Typically with slices, you don't store a position (sometimes), you just 
divvy up the slice into pieces you care about.

It all depends on what information is important.
