What the current POV calls "parsing" isn't what things like ANTLR do.
"Parsing" (in the non-POV sense) means building a data structure
isomorphic to the input source code. "Parsing" in the POV sense includes
things like executing the while loops, while in the ANTLR sense it does
not. So with a parser generator, you'd have three phases: parsing
(fast), evaluating (putting together all the objects in the scene), then
rendering (calculating pixel colors).
