Hello, c++ gurus.
I have 2 questions about scope rules.
The first one: if typedef-name names unnamed class, it became class-name.
Is it typedef-name also ?
Example:
enum en {
X =1;
};
typedef class {
int a;
} X;
X becomes class-name.
If it is typedef-name also, this example is not well-formed.
If if is not typedef-name, the example is well-formed, but,
since we cannot use `class X' this class name is always hidden
by enumerator name and could not be accessed.
The second question: in ARM (9.9) and in early versions of WP
(Feb 11, 1991) it was a section "Local type names" with few
wery puzzling examples (example 2 in the WP 1991). The current
edition of the section is much shorter, and do not cover examples
from ARM. Are these rules deleted, or just moved to any general
section ? Are examples from ARM still be incrorrect according to
current WP ?
Thank you in advance.
