The same is true of the lexer, by the way, there does not really _need_ to be three versions, simply use normal string indexing code. It's not _that_ slow, and generally speaking you do not spend most of your time compiling, optimizing that case specifically to this extent seems rather excessive. Even without inlining the amount of code duplication in preprocessor.h is rather amazing, by the way. Just look for all the code skipping quoted newlines. This could be moved to a pre-pass, making all other parsing both easier to read and smaller, code-wise. But it takes time. -- Per Hedbor
