transformInternal

!! No backward compatibility guarantees !! Reuse at your own risk

Note, we tried to re-use OrderedArgsGeneratorTransformer for other operations by providing a generic transform extension method which required a newSize in addition. Yet, we ran into 3 bugs in a row, so it seems it is too dangerous to leave it into the wild. In particular one needs to take care of:

• that the newSize is actually correct (we cannot check this)

• the offset still works as it should. For instance, filtering means the offset has to happen after generation, i.e. dropping elements and this can harm performance in case there are a lot of values (which can happen easily when combining generators). The same problem applies when adding elements (e.g. via flatMap). Something like Sequence.chunked needs extra care as the resulting stream should be ordered finite, repeating after size

Use this method only if you are more than convinced that the resulting Sequence still has the same semantics as the original in terms of order, OrderedArgsGenerator.size, and a used offset
