yes, so far.

Wrong!

Yes, of course: Separate "words" such as e.g.:
  -nonewline, stderr and "hello world!"
Yes, this is the intended behaviour. And just because
args(*) is always a proper list, most of the beware's
of "eval" don't apply here.

Thus,
  eval _puts $args
is perfectly right in this context!

(*): of course only when used that way.

PS: for completeness sake:
   In 8.5(alpha) this can also be: _puts {expand}$args
   but I can't assume people new to tcl use that already.
