Abstract:
––&nda= sh;
Inline functions have favorable behavior for some kinds of ob= ject-like entities. Often, users are encouraged to use them to wrap global = variables. This has long been the status quo, despite the unnatural bo= ilerplate. Also, it does not work with constexpr, leaving a gap in the= language. This proposal defines the inline specifier on var= iable definitions to indicate semantics similar to inline function evaluati= on and linkage. More generally, this produces a facility for named val= ues, or variables that are not objects. Applications include displacing leg= acy value-like macros and introducing data-like class interfaces without im= pacting layout.
