typedef haxe.PosInfos

PosInfos is a magic type which can be used to generate position information into the output for debugging use.

If a function has a final optional argument of this type, i.e. (..., ?pos:haxe.PosInfos), each call to that function which does not assign a value to that argument has its position added as call argument.

This can be used to track positions of calls in e.g. a unit testing framework.
