The implementation of the upfront constructors involves doing three things:
* Validate the arguments given to construct the intended type of AST is valid.
* Construct said AST type.
* Lock the AST (set to readonly) and return the valid object.
If any of the validation fails, it triggers a call to log_failure with as much info the give the user so that they can hopefully
identify the issue without having to debug too much (at least they can debug though...)
The largest of the functions is related to operator overload definitions.
The library validates a good protion of their form and thus the argument processing for is quite a bit.
