Is .reserve()’s argument scaled by the entry size after it is

I’m not sure whether the runtime has a knowledge of the
element type so maybe it doesn’t know anything about scale
factors, not sure.
length, reserve, and capacity all use the same unit, which is
elements.
reserve passes a TypeInfo instance to the runtime so that it
knows the size of the elements. You can see the implementation
here:

Many thanks Paul, I should have found that!
