Hi Wolfgang,
thanks for  the answer. In the first place I also  came up  with a
similar solution  to yours. But  that's what I meant  by ”manually
counting” and  wanted to avoid.  Apparently I missed  the obvious,
there is no special magic needed:
% doesn't seem to be necessary
% \definedataset [test]
\setdataset [test] [foo] [foo=first]
\setdataset [test] [foo] [foo=second]
\setdataset [test] [bar] [bar=first]
\setdataset [test] [bar] [bar=second]
\setdataset [test] [bar] [bar=third]
\starttext
       foo is: \datasetvariable{test}{foo}{foo}\crlf
       bar is: \datasetvariable{test}{bar}{bar}
\stoptext

Two-pass data is data that can be accessed before it has been created.

Hm how can  something be read "before* being created ?
(super-luminal neutrino  is not anymore a valid answer ...)
