The intention was to stick with things that could be parsed quickly and
easily, without relying upon slow library code. Whether that's still an
issue these days what with the Portage people who were saying that the

The only specification-compliant yaml parser is written in C, has
only the bottom two layers of the stack and no usable external
bindings... Perhaps you mean "something that's basically yaml except
with reserved string-start characters not handled correctly", in which
