node `--experimental-require-module` issue with dependency between `pkg-types` and `mlly`

[sxzz]

Environment

node: v20.17.0

Reproduction

// test.js
import 'pkg-types'

And run node --experimental-require-module -e 'require("./test.js")'

Describe the bug

pkg-types and mlly are circular dependencies, causing a stack overflow when the --experimental-require-module option is enabled.

Node.js v20.17.0

Thanks for report. I'm aware of this but both ESM and CJS loaders are supposed to support circular dependencies. In fact, the core of Node.js has many of them!

It seems an implementation issue to me with node --experimental-require-module flag..

We can fix it somehow (and as a bonus gain little of loader perf): https://github.com/unjs/mlly/issues/274

it is still a node.js bug..

Fixed in latest v22
