In using it in a named association array aggregate, its semantic are "and" =
--- e.g., some_1D_array :=3D (1 | 3 | 7 =3D> 5, others =3D> 10) sets elemen=
ts 1 and 3 and 7 to the value 5.  In a case statement, its semantics are "o=
r" --- e.g. when 1 | 3 | 7 =3D> ...  any of the values 1, 3, or 7 for the c=
ase expression will select the ... code for execution.  Is there a single n=
ame for that symbol (the |  ) that seems to have different semantics depend=
ing on context?
