If I pass a pointer and a 10u 0, my data can be 4GB in length (it's
restricted only by the size of the length parameter). VARYING seems
different. If I could say that my field was a 4294967296a VARYING, that'd
be great, but I don't think I can. The D spec length field isn't wide
enough.

If I'm stuck with passing an options(*varsize) field, I don't understand
what the length of that field should be. It doesn't seem to be a minimum
or maximum (or anything).
