The issue you're actually dealing with here is that bun doesn't read pipes/FIFO streams as modules to load, I also don't think it's following symlinks for the given file descriptor (which is a symlink to a symlink of a pipe, eg. https://github.com/nodejs/node/issues/18255#issuecomment-358991562). If you use the synchronous process substitution like so it works:

$ bun =(echo "console.log('hello')")
hello
