Yes indeed you are right, sorry for the confusion - just a stupid mistake.
I had in mind an (irrelevant to this problem)  possibility to use
Function[Null, body[##],Attributes] to give attributes to pure functions
defined with slots, which I believe is an undocumented feature (at least,
according to Roman Maeder as of v.4 - may be now it is, but I did not see
it).

Leonid
