If you think that's bad, just representing C++, not even parsing it, in Clang, takes 61K lines of headers! If you look at these files it's mostly declarations and one-line functions. It's not even doing anything. The lexers and parsers are a whole other story, certainly greater than 19K lines combined. ~/src/cfe-3.8.0.src/include/clang/AST$ wc -l *.h 2742 DeclObjC.h 2809 RecursiveASTVisitor.h 2927 DeclTemplate.h 3198 OpenMPClause.h 3249 DeclCXX.h 3800 Decl.h 4154 ExprCXX.h 4942 Expr.h 5723 Type.h 61525 total
