            Bug ID: 99597
           Summary: Parameter packs not expanded in lambda template list
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

The following code intends to work, even if it fails in three major compilers:

template <typename... Ts> 
void f(Ts...) {
  ([]<Ts>(){}, ...);  
}

int main() { f(0, 0.5); }
