            Bug ID: 47161
           Summary: clang-format does not handle semicolons in template
                    argument lists
           Product: clang
           Version: trunk
          Hardware: PC
               URL: https://reviews.llvm.org/D79773#2141164
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org
          Reporter: johelegp at gmail.com

This is how semicolons in template argument lists are formatted with the
default configuration:
```C++
template <auto> struct X {};

struct Y : X < [] {
  return 0;
} > {};

struct Z : X < decltype([]
{
  return 0;
}){} > {};

struct W : X < requires {
  ill - formed;
} > {};
```
These uses will become more common in C++20 thanks to the used features.
