How much of a performance hit are we talking about? Is the difference between using an interface and not using one noticeable?
It can be huge difference if you take inlning in mind. LDC is capable of flattening most simple range-based pipelines into simple in-place loop during optimization - something you can't do with interfaces unless some sort of runtime profiling optimization is involved.
