No. But it allows you to keep text as text, not as streamed value. I don't
know if assigning a string to a variant is copy-on-write though.

If you don't operate much on it, it doesn't matter. But the above sounds
like you do most of the work on text, not binary blobs.

They didn't ask what you wanted to do exactly either :-)

variants support most base Delphi types, afaik including class , interface
and dyn array.
