As could all of ours . . . however, many of us in the enterprise space don't have much choice as to the form of data we have to consume from outside services, so the point of making good low-friction tools part of the language (with no code generation) is to let you interact with those things without going completely insane.

Totally.

Unfortunately, many people often have to consume both, and the Gosu typeloaders make that as painless as I've seen it.

There's another project working on a YAML schema typeloader (I'm totally unfamiliar with that) and you could write a YAML structural type loader as well, depending on tastes.
