Interesting. I wouldn't have guessed this. At least in Perl, regexp
operations are usually close to pure C. Not often the source of
bottlenecks unless the regexps are poorly written.

What are symbols?

I see no reason for not putting lots of types in the repository. That's
what it is there for. The common wisdom is that type checking is done at
the loader level though. If your loader is designed for multiple
inheritance, then you can simply add a new type class as new types are
added, without have to change the parser or core loader.

I am not suggesting that requiring a loader class effect the whole
system. That's ludicrous. Each YAML Load operation is done from a
particular YAML::Loader object. That Loader object may inherit certain
properties (like implicits) from various Loading classes, but it has one
predictable beahviour.

In fact if a load operation involved another load operation (like with
!include processing) then a separate loader object would be used. And
that separate object might be from a completely different class.

Silly programmer, there's no basement in the Alamo, er I mean, there's
no finish line.

Anyway, you and I are the only ones currently implementing YAML stuff,
so we really shouldn't fight. It's all about peace and love.
