After just a little more thought let me answer my own question.

a. The as.vector() function is designed to strip off everything extraneous and 
leave just 
the core.   (I have a mental image of Jack Webb saying "Just the facts ma'am"). 
  I myself 
use it freqently in the test suite for survival, in cases where I'm checking 
the corrent 
numeric result and don't care about any attached names.

  b. is.vector(x) essentially answers the question "does x look like a result 
of as.vector?"

Nevertheless I understand Roger's confusion.
