[SR-Users] $(hdr(name)[N]) question

[Juha Heinanen]

wiki was this related to $(hdr(name)[N]):

  If [N] is omitted then the body of the first header is printed. The
  first header is got when N=0, for the second N=1, a.s.o. In case of a
  comma-separated multi-body headers, it returns all the bodies,
  comma-separated.

i don't understand the last sentence. how can i get all bodies of all
headers of name=x as a comma separated list?
