Oh, I don't know about that. Forth words can take control of the input stream! The ordinary parser eats space-deliminated tokens, sure, but how does the " word work? It takes over the input, and reads until it finds a terminal quote! It's wild: learning forth, you get used to RPN... but then you can implement an infix parser, and your "forth" can bootstrap a C-like language all in one source file. |
