Why not creating a DLL/so based Lexer/Parser based on the existing DMD
front end.? It could be always up to date. Necessary Steps. functional
wrappers around C++ classes, Implementing the visitor pattern (AST),
create std.lex and std.parse..
my 2 cents

To that end, I think we need a lexer for the standard library -
std.lang.d.lex. It would be helpful in writing color syntax highlighting
filters, pretty printers, repl, doc generators, static analyzers, and
even D compilers.
It should:
1. support a range interface for its input, and a range interface for
its output
2. optionally not generate lexical errors, but just try to recover and
continue
3. optionally return comments and ddoc comments as tokens
4. the tokens should be a value type, not a reference type
5. generally follow along with the C++ one so that they can be
maintained in tandem
It can also serve as the basis for creating a javascript implementation
that can be embedded into web pages for syntax highlighting, and
eventually an std.lang.d.parse.
Anyone want to own this?
