Yes, that’s a promising direction. And this is surely the motivation why the
C# folks picked “struct”; they wanted to carry the connotation that this is a
structure that is inlined. Problem is, the word “struct” is already so heavily
polluted by what it means in C. So perhaps something like:
inline class V { … }
This says than a V can be inlined into things that contain a V — other classes
and arrays. It also kind of suggests that this thing has no intrinsic
identity.
A possible downside of this choice is that one might mistake it for meaning
“its methods are inlined”. Which is actually a little true, in that the
methods are implicitly static and therefore more amenable to dynamic inlining.
So that might actually be OK.
