A convenience parser for regular expressions.
This parser takes as input a regular expression pattern string (the "concrete syntax") and returns a high-level intermediate representation (the HIR) suitable for most types of analysis. In particular, this parser hides the intermediate state of producing an AST (the "abstract syntax"). The AST is itself far more complex than the HIR, so this parser serves as a convenience for never having to deal with it at all.
If callers have more fine grained use cases that need an AST, then please
