hubert.reinterpretcast added inline comments.
================
Comment at: clang/test/SemaCXX/constant-expression-cxx2b.cpp:219
+ NonLiteral n; // cxx2b-note {{non-literal type 'NonLiteral' cannot be
used in a constant expression}} \
+ // cxx2b-warning {{definition of a variable of non-literal
type in a constexpr function is incompatible with C++ standards before C++2b}}
return 0;
----------------
Not sure how much we want the message in this case. The lambda is not marked
`constexpr` (although it is implicitly `constexpr` in C++2b).
Note that we don't get a message for this:
```
auto qq = [] { return 0; static int x = 42; };
constexpr int qx = qq();
```
I am not sure how difficult it would be to come at this from the
used-in-constant-evaluation side, but there is probably a larger class of
messages in the same situation (so it would probably be a separate endeavour).
