I took this PR for a spin and it still seems to be failing with the example I posted in the issue. I'm running on Mac, so maybe that's related? Could also be a problem with how I built (I can't seem to verify after the build that ./deno was built from the right commit hash). However, I do have 6700ca8cc1b007a9aeae688fd31c75a86cd717c7 checked out and cargo clean && cargo build didn't produce any errors, so I'm fairly confident I have the right bits.

Actually, I can confirm that my custom built deno is in fact being used for deno compile, but I'm not sure that my custom built deno is being used as the runtime for the compiled artifact. Changes I made to cli/standalone/file_system do not seem to be reflected in the compiled executable. Would that make sense? Is there something I need to do during deno compile to ensure that I'm picking up the latest changes to the standalone runtime?

@irbull you need to set the DENORT_BIN env var (see #27015 (comment) for example)

Thanks David, that works! Google for DENORT_BIN produces no results, so I guess it's not documented. I've filed #27035 to add it to the docs. Feel free to add my face to that issue and I'll put together a PR.

As for this issue, with a a customer DenoRT, I can confirm that this PR addresses the issue. Furthermore, if you actually try and load the bundled .ts file you see the TypeScript (not the transpired JS). Good work.
