Allen,


What is important for the parser is the nature of the grammar of the
language. The grammar class determines the kind of parser you have to
build. This is orthogonal to the paradigms a language offers. The
latter define the semantics of a language. They will influence the way
you build certain data structures while parsing and how you use these
during verification, optimization and code generation. The parser as
such doesn't need to know if a language is imperative, functional,
applicative, etc. It must only build a parse tree.
