Ser(Vecsmall(0))

[Michael Somos <somos@grail.cba.csuohio.edu>]

Currently Ser() can't deal with Vecsmall:

? Ser(Vecsmall(0))
  ***   at top-level: Ser(Vecsmall(0))
  ***                 ^----------------
  *** Ser: incorrect type in gtoser.

I see no reason that it should be any
different than with Vec. Similarly:

? lex(Vecsmall(1),Vecsmall(2))
  ***   at top-level: lex(Vecsmall(1),Vecs
  ***                 ^--------------------
  *** lex: incorrect type in comparison.

I see no reason that lex should have
a problem comparing Vecsmall. Shalom,
