--- Comment #1 from Frank Heckenbach <f.heckenbach@fh-soft.de> ---
Probably the same bug in a slightly different form:
% cat test.cpp
template <typename> struct S { };
template <int> using A = S <decltype ([] { })>;
template <int d> using B = A <d>;
B <0> a;
% g++ -std=c++20 -Wall -Wextra test.cpp
test.cpp:4:1: error: 'B' does not name a type
4 | B <0> a;
| ^
It works when using A instead of B.
It works when using an alias for "decltype ([] { })".
Other compilers accept it as is.
Also, I find the message confusing (even if it was rightly rejected): Of
course, 'B' does not name a type. It's followed by template arguments, so 'B'
shouldn't be a type, but a template or template alias, or 'B <0>' should be a
type.

Note clang rejects the original testcase in comment #0 but EDG, MSVC all accept
it. Plus GCC now accepts it on the trunk.
So closing as fixed.
