  The gut reaction of a shell programmer will probably differ, but
  I'd rather not change the syntax.  To me, string scanning and
  variable extension are different stages and must not affect each

duly noted.

  If you do change the syntax, where do you stop?  Why should \ be
  special for variable syntax, but not for :regex and :matches
  pattern syntax?  I don't want to have to answer that.

interesting point!  I'm not sure I want to explain that, either :-)
