right now they implement 20 ish functions to support "random 
access ranges" and can have drastic differences if you dont met 
something like "bidirectional" which is why some of the range 
functions are like 300 lines long

yes, template hell is part of this

I would hope to make it simpler then 20 functions, but I dont 
know.
