[High Performance Coder]

Compilation times in functional have blown out with the use of variadic template programming, and becoming unacceptable for Python/RESTProcess descriptors. Check out the following resources to see if we can improve this.

https://thephd.github.io/sol3-compile-times-binary-sizes (The rule of Chiel)

There is a lot of room for improvement, but it is also a deep rabbit hole!
