Only tried with v originally, then decided to try translating to other langs... same error. So it's not the output type that matters, only the contents of the python script being translated.

@JalonSolov Only the Dart backend seems to support string multiplication from what I can see from tests/test_unsupported.py:204. I've created a PR to add support for the V backend but that file needs some work before it could be transpiled. (file needs some type annotations, object subclass is redundant now, backends will still stumble on something like lambdas)

V should be fairly easy to support for that - turn it into a .repeat() call.

I tried with Go and Nim and got the same error, but it appeared to work with Rust. At least it generated a file with no error messages.

See #553.

I'm surprised, does the generated file actually work?

[JalonSolov]

I don't do Rust, so I have no idea. :-)
