  low-level library for minimizing the size of your types (by foonathan)

I actually came across the term "tombstone" before, in the "foonathan/tiny" library. I found that one after I started building tiny::optional, and it seems to have similar use cases, but also seemed abandoned and not to implement a fully fledged std::optional replacement. So maybe he got the idea from the talk by Arthur O'Dwyer.

  Replacement for std::optional that does not unnecessarily waste memory

tiny::optional is a header-only C++ library for x86/x64 intended to be a drop-in replacement for std::optional with the twist that it does not require additional memory for bools, floats, doubles and raw pointers. For example, a std::optional has twice the size of a raw double because of 7 padding bytes after the internal bool. These wasted bytes can have a notable impact on performance in memory bound applications. On the other hand, a tiny::optional has the size of a double by exploiting unused bit patterns (i.e. by exploiting platform specific behavior).
