had put this off because it breaks history but now the references to register stuff which builtin is off course full of, become much shorter

Builtin module
The Builtin module contains functions that can not be coded in ruby. It is the other side of the parfait coin, part of the runtime.
The functions are organized by their respective class and get loaded in boot_classes! , right at the start. (see virtual/boot.rb)
These functions return their code, ie a Virtual::CompiledMethod object, which can then be called by ruby code as if it were a "normal" function.
A normal ruby function is one that is parsed and transformed to code. But not all functionality can be written in ruby, one of those chicken and egg things. C uses Assembler in this situation, we use Builtin functions.
Slightly more here : http://salama.github.io/2014/06/10/more-clarity.html (then still called Kernel)
The Builtin module is scattered into several files, but that is just so the file doesn't get too long.
