Will this compile in Python too?

[kaizencc]

It passes rosetta:extract --compile so it should. However, this entire PR is waiting on a fix in backup I'm going to make very soon (which is why build is failing).

edit: nevermind, no fix necessary.

This won't work actually. If Rosetta doesn't flag this, that's a bug in Rosetta.

You need to declare an explicit class that implements the right interface.

@kaizen3031593 for context: #17928

[kaizencc]

Rip rosetta. I can investigate what is going on in rosetta later. In fact, I looked back at what I did in lambda-go which also included a bundling function. I recall that rosetta:extract --compile did not pass there and what I did was end up making that example a text snippet and say that the snippet is only available in TypeScript.

Which I guess is bad for the Python folks because I'm basically saying, sorry this doesn't work in Python.

That seems to be what #17928 tried and it did not work.

I ran s3-assets with the latest version of rosetta:extract and confirmed that this updated example compiles (according to rosetta). Since we're worried about python translations, here it is reproduced:

@jsii.implements(ILocalBundling)
class myBundle:
    def try_bundle(self, output_dir, *, image, entrypoint=None, command=None, volumes=None, environment=None, workingDirectory=None, user=None, local=None, outputType=None, securityOpt=None):
        can_run_locally = True # replace with actual logic
        if can_run_locally:
            # perform local bundling here
            return True
        return False

assets.Asset(self, "BundledAsset",
    path="/path/to/asset",
    bundling=BundlingOptions(
        local=my_bundle(),
        # Docker bundling fallback
        image=DockerImage.from_registry("alpine"),
        entrypoint=["/bin/sh", "-c"],
        command=["bundle"]
    )
)

I think this looks good to go. The rest of the PR should still be gtg as well.
