John!  Here I was certain you would agree, like with make-vector and

Right, I was just exploring the implications of naming something

For example, let's say I provide a primitive implementing the mmap
syscall, and have it return a blob.  Perhaps I would like to expose a
range of that memory to a procedure, and allow it to set the memory.  I
want a shared-state sub-blob, but "sub" really doesn't combine well with
"blob".  Dunno!
