Doubt on using polymorphism in coding an expression parse tree/evaluator
I am working on an interpreter for a toy language, just to learn about building an interpreter. I have already implemented a simple parser for the grammar that generates a parse tree. Now, the usual way of evaluating the parse tree would be to use polymorphism on the nodes of the parse tree, with code that looks something like below (in ...

It looks like ANTLR's tree grammars operate on hierar...
