I'd probably prefer a tokenizer/lexer as the lowest layer, then SAX and
DOM implemented using the tokenizer. This way we can provide a kind of
input range. I actually used Brian Schotts std.lexer proposal to build a
simple JSON tokenizer/lexer and it worked quite well. But I don't
think std.lexer is zero-allocation yet so that's an important drawback.
