sol2/sol/overload.hpp
ThePhD 27174aba9c This mega-commit produces simple_usertype to allow for faster compile times by avoiding the use of __index internally. It sacrifices some speed and some storage optimizations and also does not allow variable syntax, but the produced table is directly modifiable.
Adds a `protect()` function to trigger safety for an item.
This commit also optimizes away all instances of virtual function calls for function calls and storage. Will need to test speed to see how it works out.
