* This is a special file that bootstraps the compiler
* If you are using a string use 'Append' instead of '+=' otherwise the runtime will crash
* You only have access to classes within this file, so you are unable to use collections
* Return values are not checked as values may come directly from VM system calls
* Bootstrap directives for the VM an TRAP instructions are frequently used, you will have 
* to dig into the VM code to figure out what is going on.
* Primitive classes such as 'Int', 'Bool' and, 'Bool' start with at '$'
