Seems kind of odd.. put is implemented as an append method for some custom
types, e.g. std.array.appender. But for arrays put just removes Item or
RangeLength number of elements from the array. What's the use case for this?

This should probably be in a FAQ somewhere. :)

Thanks, that post explained it. Obviously I wasn't the first and
likely won't be the last person to run into this. Maybe put's
documentation could make a note of this.
