I can't speak to phobos but you should achieve this behavior in 
mach.range.split by changing just one line (I'll add some cleaner 
support for this myself sometime soon using a template argument, 
maybe later today?)

https://github.com/pineapplemachine/mach.d/blob/master/mach/range/split.d

Change line 127 from

     this.segmentbegin = this.delimindexes.front + 
this.delimlength;

to

     this.segmentbegin = this.delimindexes.front;
