There are also some constructions with a "::" (C++), a "'" (Ada)
and a "!" (Visual Basic). These are similar that they provide a
kind of attribute, but with some sort of variation. As far as I
C++ ns::a provides an identifier in a namespace (i.e. the "::" is
resolved at compile time).
Ada x'max [I think] provides a static attribute of "x" such as
the largest value it can take (i.e. the "'" is also resolved at
Visual Basic rs!v is used for (among other things?) accessing a
value retrieved from a database. rs.EOF would provide an
attribute of the whole read (whether it is at end).
Hope this helps.
