Yeah @marker_line_index would work fine, or just @marker_index. 

Would it be possible to do data-defined overrides of certain marker
properties of individual markers, based on this @marker_line_index? Say
each odd index would have different offset as each even index - or
change color or font-marker content based on this index?
