- 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.
