In Chomsky's hierarchy, the set of recursive languages is not defined. I know that recursive languages are a subset of recursively enumerable languages and that all recursive languages are decidabl...

The syntactical grammar of hardly any programming language is regular, as they allow arbitrarily deeply nested parenthesis. Rust does, too: let x = ((((())))); But is Rust's syntactical grammar ...

I'm trying to understand the four different Chomsky language types but the definitions that I have found don't really mean anything to me. I know type 0 is free grammar, type 1 is context sensitive...
