I think we are talking about two different things here. The switch-case
statements in the parser do neither emulate nor replace or in any other way
simulate anything even remotely like dynamic binding: Remember, the POV-Ray
scanner and parser are a standard recursive decent implementation, and
interpretation of a language requires staged conditional code execution.
There is no place for dynamic binding in a parser for those tasks, it is
just a completely different technique which has no application here.
