yes, and yes:
1) I dont't want the ")" to be inserted for me, rather type it
   myself, and as such a functionality like  "close current snippet"
   seems natural.
2) This should all be configurable.
  Maybe really convenient would be a scheme similar to the 
  'ess-style' (and corresponding  ess-style-alist in  ess-custom.el)
  where choosing one style sets *sevaral* configuration
  variables at the same time.
  In this case, the combined behavior of
   - do *not* put the ")" for me
   - assign "close-current-yasnippet" to  ")"
   - .... {...}

  could be part of the   yasstyle-old-habits-dont-die   :-)
  for people like Rodney or me ..
