[libcxx-commits] [PATCH] D118188: [libcxx] [Windows] Pick a unique bit for __regex_word

[Arthur O'Dwyer via Phabricator via libcxx-commits]

Quuxplusone added inline comments.


================
Comment at: libcxx/include/__locale:548
     _LIBCPP_INLINE_VISIBILITY ctype_base() {}
 };
 
----------------
Could we realistically put a future-proofing `static_assert` down here, something like
```
static_assert(__regex_word & ~(space | print | cntrl | upper | lower | alpha | digit | punct | xdigit | blank) == __regex_word);
```
and I would expect
```
static_assert(upper | lower == alpha);
```
also? And/or, could we make a test for this?
