Should we add drop to Phobos?

I personally like immutable methods way better than a ref changing
function like popFrontN.
As you pointed out writing str.find(";").drop(2).find(";").drop(2) is
cleaner than writing this with popFrontN.
Drop will have issues for input ranges.
Adding a ref count parameter overload to let you know how many elements
were dropped/not dropped seems too messy. No idea for that one.
The documentation should clearly state that this offers similar
functionality to popFrontN but it's purpose
is to enable a different syntax so that people don't get completely
confused.
