Hey @moltar, added this out of interest last night so I've opened a PR.

The tests are just a copy & paste of zod's test, since drop-in compat is a core goal of the project

It's fascinating how the type-checkers which require extra plugins/transpilation blow everyone else away though.

One frustrating thing, is I added strict/passthrough support and updated the library, but even after blowing out node_modules ts-node seems to be caching the old version from somewhere, so I can't actually run the benchmarks locally anymore. Have you come across this?

Have you come across this?

Hm, no, sorry. 🤔

I think CI environment should be pristine, so it will run fine there. I just approved the run.

Very weird, it's failing to check the .d.ts files from light-type in CI. Since a lot of libs are not having issues there I assume it's a legit problem, so I'll need to have a look at the build 😄
